overset mesh - collision of mesh

maxonline · February 19, 2019, 12:47

Hallo,

I basically try to simulate a stone falling into water using the overset mesh methode and OpenFOAM v1812 with the solver overInterDyMFoam. I used the floatingBody tutorial and modified it. The simulation works fine untill the the "stone" (overset patch) hits the ground (boundary of domain).
Is there a possibility to allow collision of the patches or to stop the movement of the overset mesh at a certain distance to the boundary?

The question should be: what should the overset region outside of the background mesh be? That is, what should the cells of the inner cells be whenever they go out of the outer domain?
