Re: [Question #681383]: problem of the unit of normal force in Law2_PolyhedraGeom_PolyhedraPhys_Volumetric


Question #681383 on Yade changed:

    Status: Open => Answered

Bruno Chareyre proposed the following answer:
Hi, I'm not expert of Polyhedra code but it seems you are trying to question a constitutive assumption mainly.
If someone assume that Fn is proportional to intersection's volume then Fn=k*volume, and it _follows_ that k is in N/m^3.
You can't assume upfront that kn is a pressure regardless of the constitutive framework (usually it's not, anyway, it tends to be a force per length).
