MPM processes ​

Note

This package provides an explicit MPM solver.

We classify MPM processes based on stress update schemes. Generally, the stress update schemes include:

  • USL

  • USF

  • MUSL

  • AFFINE

Here, AFFINE[1] is an exception; it does not represent a stress update scheme, but since we have only implemented one stress update scheme for AFFINE, similar to USF, it is also an option.

This implementation is located under the /src/solvers/ path, you can see some files like **_MUSL.jl. We just need to rearrange/modifiy the kernel functions, super easy! 🎸
