Hi,
I'm having some issues with the ConstraintModel and the NodeTriangleConstraintList: I created a simple model where a steel slab should shift on another one, using the NodeTriangleConstraintList to describe the interaction between the surfaces. The lowest surface of the bottom body cannot translate nor rotate.
If the bodies are both rigid, the simulation works.
If only the top body is rigid, the simulation runs but it gives good results only when the MaximumTimeStep is very low and the density of the steel is high (more than 60 g/cm3).
If the top body in not rigid, the simulation runs but the results are all zeros.
Furthermore, I don't understand why the simulation runs only when the surface of the top body is the Slave and the one of the bottom body is the Master: since I apply a displacement on the top body, shouldn't it be the Master? If I try to switch them I get a Fatal Error 11 "Exception type: Segment violation".
Is there something wrong in my model or am I missing something?
Thanks, Michele
