I have been trying to implement the J integral for an isotropic FGM based on the following paper

Hi I tried to code a basic phase field model for fracture in octave.

It doesn't seem to converge to the correct load. It fails later.

Also mesh refinement did not improve the results.

The link to the GIT is here

Any idea where I am wrong?

Ping me. Thanks in advance.

Is it possible to simulate air flow over objects of unconventional geometries (curved solids) using Abaqus?
