Chareyre proposed the following answer:
1) Yes it should be possible Everything looks correct.
The fact that it has no effect is probably only due to your constitutive parameters.

If you really type [Ip2_FrictMat_FrictMat_MindlinCapillaryPhys()] in your script, then clearly there is no rolling friction (inspect parameters of this functor and default values, you will see).
Else, open inspector and check the values of moment in interactions, you will see if  they are really zero or just very small.

Note that it is useless (even if harmless) to define a cohesive
material. A FrictMat should be enough.
