### Postprocessing of FEM: extremely slow speed of NIntegrate

I've gone through the documentation for NDSolve FEM. There are quite a lot tips and techniques for accelerating NDSolve, and only quite few tips for post processing. Somehow I found out that the ...

### Using My own colorfunction in SMTShowMesh

When plotting the data using SMTShowMesh in AceFEM package I would like to use my own color function not the one that SMTShowMesh uses by default. For this to be achieved, I created my own color ...
