CalculiX is a package designed to solve field problems. The method used is the finite element method. With CalculiX Finite Element Models can be build, calculated and post-processed. The pre- and post-processor is an interactive 3D-tool using the openGL API. Calculix.jl wraps original code to Julia environment.
I did initial diff already. Most of the files are changed. This can be very easy or very laborious depending how much changes there have been made for the sources when uploaded to the JuliaFEM/CalculiX-cmake repository.
Also the build.jl script should run these tests after compiling. There's a compare shell script, which can be edited to run the test, at least in unix like systems.
