ProblemType

Data > Problem Type > Load > ULFapplication/custom_problemtype/ULF_FSI_INC.gid


Geometry

(how to create the geometry - read the general GID tutorial)


Boundary Conditions

Data > Conditions > Fluid Boundary Conditions , Select Surfaces , 

Assign to Fluid Surfaces: 1.Body force (Y= -9.8) 2.Density 3.Viscosity 4.Bulk Modulus (-100 for fast convergence , If you have time or powerful processor it's better to assign -10^5)

Assign to Structural Surfaces: 1.Is Structure 2.Displacement (X=0 , Y=0 for Fixed Surfaces) Fluid Boundary Conditions , Select Lines ,

Assign to The Fixed Line of Structure: Displacement (X=0 , Y=0)


Element Types

Data > Conditions > Element Type , Select Surfaces

Assign "TotalLagrangian2D3D" to Structural Surfaces

Assign "UpdatedLagrangianFluid2Dinc" to Fluid Surfaces


Materials

Data > Materials > Solid\Fluid


Saving

Save the Project


Meshing

(how to mesh - read the general GID tutorial)


Calculating

Calculate > Calculate Windows... > Calculate


Final Step (Renaming)

Open the saved project in windows explorer (.../Example.gid) and Change the names as followed :

Example-6.dat --> Example.py

Delete "_fluid" from the names of the files which created after Calculate.
