EDEM API: How to get interaction parameters

Hello,

I'm working on a Coarse Grain contact model and  I need to input the scaling laws in my custom contact model code with EDEM API. Some of these rules need parameters of interaction between particle-to-particle during particle-to-wall contact, so I can't get the parameters that I need using the "interaction" argument of "calculateForce" function.

Is there any way to get the interaction parameters between two elements at the beginning of the simulation before any contact occurs?

Thank you in advance.
