How to generate the grid and material points

Hello, developer
I am confused that how to generate the grid and material points for a specific boundary value problem. It seems that the user documentation of CB-Geo MPM does not mention the generation of grids and material points. Thanks.
Best regards.

Hi @Tong-SJ

We don’t have a mesh generator at the moment. The Mesh file is an ASCII Format as shown here: https://mpm.cb-geo.com/#/user/preprocess/ascii-mesh-particles You can generate it writing a simple script.

However, particles can be generated using the automatic generator and the particles can fill the entire mesh space or a selected sub-set of the mesh.
