Developed Software

Discontinuous Element Insertion Program (DEIP)

DEIP is a MATLAB/OCTAVE toolbox for inserting zero-thickness elements into a continuous finite element mesh in two and three dimensions. These elements are used for intrinsic cohesive zone modeling and for the Discontinuous Galerkin method. The algorithm is topology based and is suitable for complex, unstructured meshes.

The code is under continual development and currently has capabilities for the following element types:

  • Two-dimensional meshes: 3, 4, 6, and 9-node elements
  • Three-dimensional meshes: 4, 5, 6, 8, 10, 14, 18, and 27-node elements

Test out the code online through the capsule at CodeOcean.com!

The code is compatible with WINDOWS and LINUX operating systems and both MATLAB and OCTAVE computing environments. Additionally, the toolbox contains a small linear finite element program and plotting functions for MATLAB, as well as interfacing scripts for passing data between Abaqus input files, Gmsh mesh files with Code_Aster compatibility, and Paraview visualization files.

Current distribution: Version 3.0, released December 20, 2019
