[Getdp] Constraint problem with elasticity/mechanics

[Arkadiusz Wasylkow]

Dear gmsh/getdp users,

I have no idea how to treat constrain problem: Limit the displacement of
elastic membrane - when displacement is high enough, membrane should touch
the wall and not move any further in that direction. How to implement this ?
I saw that constraint can be a fixed value or  a initial value - both seems
to be not useful in this case.

Thanks in advance
