Hi,

I'm trying to understand how to use APDL to solve a simple dice-shaped volume. I just need to understand the basics.

I put my script inside the Mechanical solution section and set an area as a fixed boundary condition and an area force on the opposite side. The geometry is imported as an IGES file.

The .iges file gets imported, but the geometry section in the tree is still empty, therefore I need to link the geometry inside Workbench to the mechanical analysis. But why? It should be done by the APDL script itself.

Furthermore, Mechanical tells me to add at least one structural load in the tree on the left side manually to make it work, but I did that via APDL?

Inside MAPDL, it's working so far, but inside Mechanical, it is not. So what did I miss?

 The Workbench Mechanical application (i.e Static Structural) only uses the APDL as a solver.
 It is not possible for the Tree to be created from APDL code.
