xpfem

A Python package for finite element method (FEM) in solid mechanics

You should download all the code and install the following packages:

• numpy
• scipy
• pyvista

Features:

• linear elasticity
• 2D Quadrilateral element (Q1,Q2)
• 3D Hexahedral element (Q1,Q2)
• BBar element for 3D Q1 element
• Perfect post-processing
• Export VTK file

Run code

You can install the packages by

1. pip install numpy
2. pip install scipy
3. pip install pyvista

Run the test.py or other test file, you can get the displace and stress as following
