Is there any documentation for this solver? Or do I have to go through the source code to work out what parameters may be set, with relevant keywords? I have read Daniel Brennan's thesis but didn't locate any relevant 'using FOAM' material.

The solver is not documented to my knowledge, so you have to refer to the code and tutorials for the setup.

Basically the solver assumes the multiphase system is a mixture with variable density, it treats it as a compressible single-phase system with the additional equation for the dispersed phase fraction, and it can account for the stresses in the plastic regime.

Thank you. Sadly, I cannot locate any specific tutorial. Reading through the tutorials it looks as if I may find relevant empty dictionaries. I missed them, but that may be because I am new to this.

I did try the code but found too many levels to be sure what I was looking at.

Tutorials for settlingFoam are located here:

~/OpenFOAM/OpenFOAM-1.7.x/tutorials/multiphase/settlingFoam/ras/

About understanding the code, start from the main file (.C) and look at the various included files when they are called from there. The logic of OpenFOAM solvers is always the same: there is a main file, which is typically quite short, and the actual work is split in .H files, one for each equation/block of code to achieve a specific task.

Best,
