harmonic average of stiffness between sphere and wall

Asked by Alsidqi Hasan

Dear Yade developers/users

How yade calculates harmonic average of stiffness between sphere and wall? In yade documentation I read only formulation between sphere and sphere. Questions:
Is the same formulation used between sphere and wall?
If yes, what is the value of r for wall in the formulation used by yade?
If no, what is the formulation?

Thank you,
Best Regards,

Alsidqi

Hello Alsidqi,
The calculation is the same, and the radius used for the wall body is
the radius of the sphere body.
