I’m creating a model of a structure built of stone arrangements. Because the number of instances is so large, meshing and analyzing the assembly as a 3D deformable body fails due to my computer’s physical memory limit of 64 GB. Is there a way to test the stability of these blocks without having to mesh them?

Hi,
It’s not possible to do this without meshing. However, I recommend using the Submodeling technique. Analyze your model with less mesh and larger meshes. Find the critical sections, then use the Submodeling technique.
Also, I have some recommendations to speed up your simulation:
- Use mass scaling if you are using the “Dynamic, Explicit” step.
- If your model is quasi-static, increase the mass artificially.
- You can change the time period and the size of the meshes as well.
You can refer to the links below to acquire more information. It’s worth a look.
