Hi everyone,
I’m having trouble implementing a contact algorithm in my numerical wave tank that uses the ICFD method. My setup has a floating body that is supposed to collide with a fixes structure, but as they get closer, there’s always an artificial gap between them that’s filled with the fluid mesh. This leads to a volume mesh error in my simulation.
Does anyone know how to avoid this problem? Or is it even possible to simulate contact between two bodies with the ICFD solver?
Any advice or ideas would be really appreciated!
Thanks!

You can try with *ICFD_CONTROL_GAP card in ICFD simulation which will allow a flow blockage between two 
surfaces in close proximity based on a user defined contact distance.

For structural simulation, you can use higher contact thickness to avoid direct contact between two structural bodies.
