In general, the process should start by creating a new geometry from scratch or by modifying or using an already existing one. For this tutorial, a group of simple entities were created which try to represent a simplified example of most of the capabilities of the program. The main objective of this document is to understand all the steps involved in assigning the corresponding properties and boundary conditions to a model and how to run a DEM simulation using the G-DEMPack package. The GiD geometry of this tutorial is available for downloading here: [[File:Dempack tutorial.zip]]. On the other hand, the user is strongly encouraged to follow any of the GiD Tutorials available [http://www.gidhome.com/support/tutorials here].
  
* Succinct explanation of the creation of geometries
 
  
We will start then by assigning the corresponding group properties. In this tutorial, a very easy geometry was created for the sake of simplicity.  Figure A2-1 shows the geometry chosen, very simple but representative enough.

Once the window is opened, we have to create the groups representing our domain. In this sample case, the following groups were created: box, inlet, outlet and fluid.
+
[[File:Dem tutorial group properties.png]]
  
We must start assigning entities to the groups. To do this, just right-click on the corresponding layer, go to assign, choose the geometry type (in general surfaces or volumes) and choose the appropriate geometry. In this case, the lower circle (surface) would be the inlet, the upper one would represent the outlet, the box would be the walls of the cylinder and, finally, the volume would constitute the mass of fluid.

Once the window is opened, we have to create the groups representing our domain. To do so, we have to click on the New icon to start adding entities. The next figure shows its location. When the New icon is pressed, an automatically named group will be created. To rename it, just click on it, modify the name and press enter to finish. Do this process as many time as needed to create the necessary groups.

We will continue by defining the properties of the fluid in the simulation. We just have to click on the icon showing in the next figure to open the menus and in particular the Materials tab:
 
  
Figure A2-4. Opening the Materials menu

In this sample case, six groups were created: two FEM walls (the belt and a box), two different inlets (one creating spheres and the other clusters) and two initial volumes of spheres. The list of group entities should be similar to the one that follow:
  
To begin inserting the fluid properties, we go to Fluid>Water and unfold the Fluid submenu by clicking on the plus sign on the right of Water. A list of parameters to fill in will unfold as. The next figure shows the details.

[[File:Dem tutorial layers and groups.png]]
  
To fill in or modify the value of the parameters, just double-click on the corresponding current data. The data above corresponds to an intermediate viscosity mud.
 
The same process can be followed, in this case, for the DEM material. We unfold the DEM-Default material submenu at the bottom of the same window and fill the fields with the appropriate data. See Figure A2-6.

We must start assigning entities to the groups. To do this, just right-click on the corresponding layer, go to assign, choose the geometry type (in general surfaces or volumes), choose the appropriate geometry in the GiD drawing and click Finish when done. The next figure shows the result of correctly assigning entities to their corresponding groups.

[[File:Dem tutorial layers entities groups 50.png]]
  
The user can also include initial volumes composed of DEM spheres.  To assign this volumes, the user must first double-click the DEM > Elements > DEM_Element section inside the Model tab. A 'Properties' window will show up open where the user will tell the program the group associated with this DEM domain and its corresponding material. See Figure A2-18 for details.

To do the previous operation, the user must first select the appropriate group and press the 'Draw groups by colour' icon to confirm the correct assignation. Press Finish when done. The next figure shows the location of the corresponding icon.
  
This volume must be discretized using an specialized sphere mesher, different from the tetraedra-based one used to handle the fluid part. This particular mesher is not used by default, so the user must tell the preprocessor that this mesher is going to be used.
 
  
To use the sphere mesher, the user must first select the DEM volume. This is done by going to Mesh > Element_type > Sphere, selecting the desired volume and pressing Esc when done. Secondly, an average radius must be chosen for the mesh by clicking on Mesh > Unstructured > Assign_sizes_on_volumes, inserting the desired size in the window that will open, clicking on Assign to select the volume and pressing Esc and Close to finish assignation.

Additional meshing settings can be set on the Preferences window. This window is accessible by clicking on Utilities>Preferences. The options are available clicking on the tree option ‘Meshing’, tree sub-option ‘Sphere Mesher’.
+
== Setting the DEM Materials ==
  
We set the fluid properties by assigning them to the Water material previously created. To do so, right-click on Properties and choose New. A New Property window will appear below. We choose Water on the label next to Material and click on OK. The properties of the fluid in the problem are those of the Water material. See next figure for details.

We will continue by defining the properties of the DEM elements in the simulation. We just have to click on the Materials tab at the top of the tree to access the Materials section. The user can modify already existing materials in the tree by double clicking on the corresponding material. He can also create new materials by right-clicking on DEM and selecting New Material. The next figure shows the window.
  
The next step is to tell the program which are the fluid elements amongst all the geometric entities. We can do so by going to Elements and right-click on Fluid. As before, choose New and a window will open up below. On the Group tab, choose fluid and click OK. The elements are properly assigned. See Figure A2-10 as a guide.

== Setting the Boundary Conditions ==
+
To create or modify the material properties, we go to the desired material and unfold its properties by clicking on the plus sign on the right of its name. A list of parameters to fill in will unfold. To edit the value of the parameters, just double-click on its corresponding current data and insert the new data.
  
Figure A2-3. Group Editor window
 
  
We now need to tell the program the model characteristics: boundary and initial conditions, inlet options, time considerations, etc. To begin filling all this data, we just click on the Model menu located at the left of the Materials tab and the Model window will show up. This menu can be accessed also by clicking on the icon showing in the next figure:

A2.7.1. DEM Inlets
 
  
Apart from setting the value of the different parameters that will show up, again we have to relate this inlet condition with its corresponding geometrical entity by right-clicking on Inlet>New and assigning the appropriate layer. See Figure A2-19 for details.
+
We now proceed to set the boundary conditions, which consist in the inlet and DEM-FEM entities. We will first start with the inlet feature. To begin filling this section, we just double-click on the Inlet label and all its properties will show up. Apart from setting the value of the different parameters that will show up, again we have to relate this inlet condition with its corresponding group at the bottom and click Ok when done.

=== Creating DEM-FEM Wall Entities===
  
A2.7.2. DEM contact with walls
 
  
By default, the DEM elements do not experiment any force from any surface of the meshed domain. If this is desired, there is an extra condition to mark the surfaces that will be impenetrable. This condition has been called ‘DEM-FEM wall’.
+
We follow by settting and assigning the properties of the DEM-FEM entities. In this case, a set of three subsections will unfold: the ‘Linear velocity’, the ‘Angular velocity’ and the 'Settings'. The next capture shows this menu and the particular settings for this simulation.
To apply this condition, just double click on the condition as shown in Figure A2-20.
+
  
Figure A2-20. Condition to set walls for the DEM and embedded structures in the fluid
 
  
A properties box is opened to fix the motion of this surface. This box has 3 labels to set the properties for ‘linear velocity’, ‘angular velocity’ and ‘Embed’.

Both ‘linear velocity’ and ‘angular velocity’ parameters can be set to be periodical, assuming that the group starts at the center of the motion with maximum speed equal to the imposed value. By default, motionless properties are imposed. I case of imposing both linear and angular velocities, the linear velocity only affects the center of rotation, while the rotation is around the updated position of the center of rotation.

Both ‘Linear velocity’ and ‘Angular velocity’ parameters can be set to be periodical, assuming that the group starts at the center of the motion with maximum speed equal to the imposed value. Motionless properties are imposed bu default. In case of imposing both linear and angular velocities, the linear velocity only affects the center of rotation, while the rotation is around the updated position of the center of rotation. Finally, in the 'Settings’ section a very useful option exists, the 'Update velocity, not Displacements', which is being used in this tutorial. When this feature is activated, the corresponding DEM-FEM entity will have a certain velocity field assigned to its nodes but no displacement will occur. As said, this option will be active for the conveyor belt layer.
Under the label ‘Embed’, the option ‘Embed this Wall in the fluid’ can be activated. When this option is active, the group marked with this condition is seen by the fluid as impenetrable also. It is actually set as a Slip boundary condition with a wall law.
+
Important note: the groups marked with the ‘DEM-FEM wall’ condition do not need to be formed by walls being boundary of the fluid tetrahedrical mesh. They can be independent sets of surfaces intersecting volumes of the fluid mesh, and the actual intersection of every triangle and the tetrahedra is calculated internally to apply the boundary condition on the fluid. Also, the group of surfaces must be closed (or near to closed allowing small gaps) if an empty body is wanted, otherwise it will be considered as an embedded membrane.

The next step is to set the values of several DEM general parameters. Check the DEM Manual Page for a detailed explanation for each of the sections. The next figure shows the chosen values of those variables for the current simulation.

Finally, the last step before launching the calculation is to mesh the whole domain. To use the sphere mesher for the DEM volumes, the user must first select the corresponding entities. This is done by going to Mesh > Element_type > Sphere, selecting the desired volume and pressing Esc when done. Secondly, an average radius must be chosen for the mesh by clicking on Mesh > Unstructured > Assign_sizes_on_volumes, inserting the desired size in the window that will open, clicking on Assign to select the volume and pressing Esc and Close to finish assignation.

An analogous procedure can be followed for meshing the FEM entities, in this case though by going to Mesh > Unstructures > Assign sizes on Surfaces, selecting the corresponding surfaces, inserting the desired value and pressing Esc when done. The next figure shows the chosen sizes for each of the entities in the simulation. Layers with no assigned size will take as mesh size the value given just before meshing. In our case, a global mesh size of 0.4 was used.
  
Finally, the last step before launching the calculation is to mesh the domain. One good way to save number of elements –and that way reducing the computational cost of the simulation- is to mesh using the semistructured option.
 
  
When it is expected that the solution flux of our simulation is going to have a preferred direction, deforming the tetrahedra in that direction will introduce very small error.
+
[[File:Dem tutorial mesh size 50.png]]
  
So it is an interesting option to strain the elements following the expected flow in order to obtain lighter and faster simulations.
 
  
To mesh following this criterion, we must go to Mesh>Semi-Structured>Volumes. A window will show up asking for the number of divisions we want to apply on the fluid volume following such direction. In the present case, we chose 2 just as an example. After filling in the desired number, we click on Assign and select the volume. To finish the operation, we hit Esc and close the window. Now we can mesh and we will obtain a mesh similar to the one in the figure:

To mesh, we have to go to Mesh > Generate Mesh, insert the desired value and click OK. A mesh like the one showing in the figure that follows should be obtained.

Introduction

This tutorial assumes that both the G-DEMPack and the GiD Pre and PostProcessor are installed, otherwise please follow the instructions in G-DEMPack installation. Please check the G-DEMPack manual page for a detailed explanation of all the fields and concepts present in this tutorial as well as for how to load the Problem Type.

Creating the Geometry of the Domain and the DEM Objects

In general, the process should start by creating a new geometry from scratch or by modifying or using an already existing one. For this tutorial, a group of simple entities were created which try to represent a simplified example of most of the capabilities of the program. The main objective of this document is to understand all the steps involved in assigning the corresponding properties and boundary conditions to a model and how to run a DEM simulation using the G-DEMPack package. The GiD geometry of this tutorial is available for downloading here: File:Dempack tutorial.zip. On the other hand, the user is strongly encouraged to follow any of the GiD Tutorials available here.


We will start by assigning the corresponding group properties. In this tutorial, a very easy geometry was created for the sake of simplicity. The next figure shows the geometry chosen, a very simple but representative enough one.


Dempack manual 02.jpg


We follow by assigning groups to the geometry. To do this, we must open the Group Editor window by clicking on the icon showing in the next figure:


Dem tutorial group properties.png


Once the window is opened, we have to create the groups representing our domain. To do so, we have to click on the New icon to start adding entities. The next figure shows its location. When the New icon is pressed, an automatically named group will be created. To rename it, just click on it, modify the name and press enter to finish. Do this process as many time as needed to create the necessary groups.


Dem tutorial group properties new.png


In this sample case, six groups were created: two FEM walls (the belt and a box), two different inlets (one creating spheres and the other clusters) and two initial volumes of spheres. The list of group entities should be similar to the one that follow:


Dem tutorial layers and groups.png


We must start assigning entities to the groups. To do this, just right-click on the corresponding layer, go to assign, choose the geometry type (in general surfaces or volumes), choose the appropriate geometry in the GiD drawing and click Finish when done. The next figure shows the result of correctly assigning entities to their corresponding groups.


Dem tutorial layers entities groups 50.png


To do the previous operation, the user must first select the appropriate group and press the 'Draw groups by colour' icon to confirm the correct assignation. Press Finish when done. The next figure shows the location of the corresponding icon.

Setting the DEM Materials

We will continue by defining the properties of the DEM elements in the simulation. We just have to click on the Materials tab at the top of the tree to access the Materials section. The user can modify already existing materials in the tree by double clicking on the corresponding material. He can also create new materials by right-clicking on DEM and selecting New Material. The next figure shows the window.


Dem tutorial dem elements materials section.png


To create or modify the material properties, we go to the desired material and unfold its properties by clicking on the plus sign on the right of its name. A list of parameters to fill in will unfold. To edit the value of the parameters, just double-click on its corresponding current data and insert the new data.


Assigning the DEM Element Entities

It is possible to create initial volumes composed of DEM spheres. To assign these volumes, the user must first double-click the DEM > Elements > DEM_Element section inside the Model tab. A 'Properties' window will open up at the bottom of the tree where the user will insert the group associated with this DEM domain and its corresponding material. The next figure shows this section in the tree.

On the other hand, details on the assignation of materials and their associated groups are shown in the figure that follows. The user must click Ok when finished.

Setting the Boundary Conditions

Creating Inlet Objects

We now proceed to set the boundary conditions, which consist in the inlet and DEM-FEM entities. We will first start with the inlet feature. To begin filling this section, we just double-click on the Inlet label and all its properties will show up. Apart from setting the value of the different parameters that will show up, again we have to relate this inlet condition with its corresponding group at the bottom and click Ok when done. The next figure shows the details.

Creating DEM-FEM Wall Entities

We follow by settting and assigning the properties of the DEM-FEM entities. In this case, a set of three subsections will unfold: the ‘Linear velocity’, the ‘Angular velocity’ and the 'Settings'. The next capture shows this menu and the particular settings for this simulation.


Dem tutorial dem bbcc.png


Both ‘Linear velocity’ and ‘Angular velocity’ parameters can be set to be periodical, assuming that the group starts at the center of the motion with maximum speed equal to the imposed value. Motionless properties are imposed bu default. In case of imposing both linear and angular velocities, the linear velocity only affects the center of rotation, while the rotation is around the updated position of the center of rotation. Finally, in the 'Settings’ section a very useful option exists, the 'Update velocity, not Displacements', which is being used in this tutorial. When this feature is activated, the corresponding DEM-FEM entity will have a certain velocity field assigned to its nodes but no displacement will occur. As said, this option will be active for the conveyor belt layer.


Setting up the General Options

The next step is to set the values of several DEM general parameters. Check the DEM Manual Page for a detailed explanation for each of the sections. The next figure shows the chosen values of those variables for the current simulation.

Choosing the Solution Strategy

This item has two subsections. On the first subsection, the user can set the type of parallel computing to use as well as the number of threads. The second subsection is devoted basically to time parameters, where the calculation delta time and the total time of the simulation can be entered. The user can also set the DEM neighbours search frequency and how often he gets information output on screen. The next figure shows the concrete values in this case.

Results Settings

In this last section the user can set the values of several parameters in relation to Results. The next figure shows the chosen values for the present simulation, as well as how the Force integration group subsection works referring to the Graphs item. Please check the G-DEMPack manual for a detailed review of all fields in this section.

Meshing and Running the Simulation

Finally, the last step before launching the calculation is to mesh the whole domain. To use the sphere mesher for the DEM volumes, the user must first select the corresponding entities. This is done by going to Mesh > Element_type > Sphere, selecting the desired volume and pressing Esc when done. Secondly, an average radius must be chosen for the mesh by clicking on Mesh > Unstructured > Assign_sizes_on_volumes, inserting the desired size in the window that will open, clicking on Assign to select the volume and pressing Esc and Close to finish assignation.

Additional meshing settings can be set on the Preferences window. This window is accessible by clicking on Utilities>Preferences. The options are available clicking on the tree option ‘Meshing’, tree sub-option ‘Sphere Mesher’.

An analogous procedure can be followed for meshing the FEM entities, in this case though by going to Mesh > Unstructures > Assign sizes on Surfaces, selecting the corresponding surfaces, inserting the desired value and pressing Esc when done. The next figure shows the chosen sizes for each of the entities in the simulation. Layers with no assigned size will take as mesh size the value given just before meshing. In our case, a global mesh size of 0.4 was used.


Dem tutorial mesh size 50.png


To mesh, we have to go to Mesh > Generate Mesh, insert the desired value and click OK. A mesh like the one showing in the figure that follows should be obtained.


Dempack manual 03.jpg


Finally, we save the model and launch the calculation by clicking on Calculate>Calculate. The user can follow the state of the simulation by going to Calculate>View_process_info. Once the calculation is finished, we can examine the results by shifting to the GiD Postprocess.


Post-Processing

Please check the GiD help documentation or the GiD tutorials for a quick view on Post-Process basic features. The next figures show some snapshots of the resulting simulation.
