Turbulence models for DPMFoam (Realizable K-epsilon model does not work)

When running DPMFoam cases, there is not much choice in turbulence models. I have added some myself to the 'DPMTurbulenceModels'. However, an inexperienced user would think that there is only 1 turbulence model compatible with DPMFoam. Can you consider adding some more common turblence models for DPMFoam? I get that this would take more compiling time, so it might not be the best solution. Another option would be to mention if you try a non-existing turbulence model that you can compile some more yourself.

My second question is regarding the use of the realizable k-epsilon model. After adding this one to 'DPMTurbulenceModels' this does not work. The solver asks for the 'k' file instead of the 'k.water' file (where 'water' is my fluid phase name). To make this compatible with DPMFoam (and other sediment solvers) the line 'IOobject::groupName("epsilon", U.group()),' should be used in the IOobject instead of '"epsilon"'. The same holds for the k-IOobject. Could you make this change so it can be used in multiphase solvers?
