Node-Face Penalty Slideline

Postby rwendner » Tue Jul 25, 2017 2:44 pm

Is there already something like a Node Face Penalty Slidesurface ?
I want to constrain a nodelist to a (plain) surface that can move and rotate. The surface could be given by a facelist, e.g. using rigid shells.

If not, would it be a lot of effort to create from the node-edge penalty slideline such a command ?

please let me know soon.

Thank you
Roman

Node-edge penalty slideline (among others) from the Stick Model Constraint List is designed for aerospace applications.

Actually, what you are asking to do can be achieved using the node-face constraint with the constitutive model we implemented for you last year (for small deformations, i.e. node stays in the initial triangle during the simulation). In this case, there is only penalty force in the normal direction, so the node can slide freely within the surface.
