This repository contains all the necessary tools to use a tetrahedral incompatible mode C1-continuous user element in Abaqus that has the following features:
- Fully compatible with C3D4-meshes
- Large strain formulation
- Simple user material interface
- 4 degrees of freedom (DOF, field value and gradient) at each corner node, i.e.~16 total DOF per scalar field
- Full 5th order polynomial shape function
- Numerical integration exact up to a full 6th order polynomial
