Setting up a constant stiffness condition(CNS) at the boundary

Asked by Akm

I am trying to set up a constant normal stiffness(CNS) condition for the direct shear test. Is there any engine specifically suited for that purpose? If not, how can I achieve this?

Hi,

There is KinemCNSEngine [*] that does that for a simple (not direct) shear box. You may take some inspiration from the code [**] if you wish to adapt it to another kind of geometry.
I'm kind of ashamed all comments therein are in French, though...

[**] https://gitlab.com/yade-dev/trunk/blob/master/pkg/dem/KinemC__Engine.cpp#L133 that is calling https://gitlab.com/yade-dev/trunk/blob/master/pkg/dem/KinemSimpleShearBox.cpp#L147

Thanks, Jerome. I think that should help me out. I will try to adopt it for my geometry. Please allow me to get back to you if I have any further questions.
