Finite element solver for Non-linear Analysis in Python and Taichi.

The following libraries are required:

• Elastic
• Elastoplastic J2
• Phase field brittle fracture
• Phase field ductile fracture

• 2D plane strain element
• 3D Hex element

• Taichi direct sparse solver
• Conjugate gradient solver

• First modify the input file input.yaml. The boundary conditions must be manually specified in the FEM_utils.py file. To run the FEM program execute main.py.
