Dump OpenFOAM matrix to mtx format (experimental)

About the Project

This is an experimental sub-project to dump OpenFOAM lduMatrix to matrix market format, which does not yet take into account of certain boundary conditions, but is sufficient as a training dataset. Figure 1 shows the mixing elbow case that comes with the icoFoam solver, and Figure 2 shows a visualization of the dumped $U_x$ matrix at the first time step.

The following OpenFOAM versions are currently supported:

• OpenFOAM-7
• OpenFOAM-8
• OpenFOAM-9
• OpenFOAM-10
