Hello everyone,

Im working on my thesis right now and simulating a fluid damper, where
I am using DFBI motion to make the piston (s. picture 1) moving and replacing my fluid volume, what should lead to a different pressure distribution inside the two chambers.
This worked well (s. picture 1) until I tried to implement some "check-valves" into this simulation. The basic idea: the 4 valves (each consisting of a plug) should move depending on the pressure distribution on the up- and downside of each plug (s. picture 2).
I wanted to realize this by using Overset-Mesh-ZeroGap mechanism of STAR CCM+, but the problem is: the whole simulation becomes unstable at the moment where the plugs are nearly to the fluid-wall-boundary and the Ze
