Incompatible mode C1-continuous tetrahedral 4-node 3D user element for Abaqus

This repository contains all the necessary tools to use a tetrahedral incompatible mode C1-continuous user element in Abaqus that has the following features:

  1. Fully compatible with C3D4-meshes
  2. Large strain formulation
  3. Simple user material interface
  4. 4 degrees of freedom (DOF, field value and gradient) at each corner node, i.e.~16 total DOF per scalar field
  5. Full 5th order polynomial shape function
  6. Numerical integration exact up to a full 6th order polynomial
