In order to achieve separation between particle class from physical method classes, I am going to clean all particles so that at last only base particles left. For this, I need to clean all functions in particles classes.

@BenceVirtonomy @FabienPean-Virtonomy Could you help to move these functions out, or I can delete if they are not useful anymore?

I agree that they should be free functions, they can be cut out of the ElasticSOlidParticles class
