On several occasions we wonder how add to our model a series of conditions such as distributed loads, Point Loads, among other things.

In this section, we'll focus more on structural aplications. For exemple, in this case we are going to put a conditios of Puntual Load. In our python file we need to add from the model part the variables or conditios that we are going to use: in this case we add FORCE or DISPLACEMENT in the main python file:

#adding Nodal Variables model_part.AddNodalSolutionStepVariable(FORCE); model_part.AddNodalSolutionStepVariable(DISPLACEMENT);

After this, we need to add the variables to the solver

#adding of Variables to Model Part should be here structural_solver_static.AddVariables(model_part)

Before in the file ( .cond and .init ) the conditions were written as follow:

# init file NODES[391](FORCE_Y,0) = 0.000000; NODES[391](FORCE_X,0) = 0.000000; NODES[391](FORCE_Z,0) = 0.000000; #cond file CONDITIONS[1] = PointForce2D([391],1);

And now in the .mpda file we can see:

Begin NodalData DISPLACEMENT_X 38 1 0.000000 358 1 0.000000 440 1 0.000000 End NodalData

Begin NodalData DISPLACEMENT_Y 38 1 0.000000 End NodalData

Begin NodalData FORCE_X 440 0 0.000000 End NodalData

Begin NodalData FORCE_Y 440 0 0.000000 End NodalData

Begin NodalData FORCE_Z 440 0 0.000000 End NodalData
