Hello,

I'm trying to run a linear forward material characterization by using commands. When I try I get this error message:

My mesh file consists of 24000 elements. I've granted MDS_driver_main.exe every possible read and write permission. Why is this not working?

    does it work in the GUI?

     

    Usually these errors are related to some non-expected behavior, such as non-periodic boundaries in your mesh, or things like that.

    In the help manual there are some guidelines on the user-defined unit cell and its requirements.

    I remember I had a similar issue once, because my mesh was not periodic.

    Where did you create your mesh?

    For the project I'm doing I'm only using commands, so I have no mic file to run. I've made it work for a 20x20x20 element mesh but it's not working for 30x30x30. I haven't created the meshes myself, that was done by my supervisor, but I assume they are created in HyperMesh.

    I'm using many element sets (each with its associated orientation); 213 element sets for 20^3 and 258 for 30^3. Is there a limit for how many element sets/associations you can use; 256 perhaps? Maybe this is the reason for the error.
