Contact with shell?

mdsimulationgroupmdsimulationgroup
I'm testing if I could do a thin shell with contact but it's giving me an error. Can a shell element be used with contact?

Thanks,
Frank

    It's supposed to work. This looks like a bug in CCX. It solves with CCX 2.16 but not 2.17-2.21 which have:

    *ERROR in add_sm_st: coefficient should be 0

    It solves OK with quadratic elements so maybe you can use that instead? Generally a good idea anyway.

    It also works if you apply the force to the elements instead of their faces. I think the reason is that on faces, Mecway generates tiny moments due to numerical error and these might be what's breaking CCX.
