Comsol FSI - one-way valve
 

Hi!
I'm trying to run simulation in Comsol od one-way valve. I use predefined FSI physics inside this software and hyperelastic material. The biggest problem i have is closing the valve. I've used contact pair, but it doesn't work. I thought the solution might be, setting minimal distance for points, but I haven't found this option. I would be very grateful for any help.
