Re: [Bug 666246] Re: periodic boundary don't work with ViscEl classes

 


        You are right, of couse.
        But how can I get shift2 in my Law* engine?

    No need here.

Why not? As I understand it, if in Sergei's law you want to use getIncidentVelocity function because you need to compute damping, then you need to get shift2 first.


I can't remember if we solved this problem : can we getVelocity without computing it twice (once in geom::update, and once in the contact law)?
I suggested to use shear/dt instead, but perhaps I missed something.
For shift2, I don't see why it wouldn't apply for facets (missed something (2)?).
