getViscoelasticFromSpheresInteraction

 

Hi there (sega),

I am not sure whether the utils.getViscoelasticFromSpheres function could not be avoided... Why not compute all relevant data in the Ip2 functor, since all the input is in input materials and other data accessible from the Ip2? The viscous constants are interaction property (not material property in the proper sense).

In Ip2_FrictMat_FrictMat_MindlinPhys for instance, restitution coefficients are specified using MatchMaker objects (see https://www.yade-dem.org/sphinx/yade.wrapper.html#yade.wrapper.Ip2_FrictMat_FrictMat_MindlinPhys), which let one prescribe different values for different material combinations easily.

Would you think that this would be a viable solution for your viscoelastic model as well?

Cheers, vaclav
