Hey everyone,

I got a case of a cave system which is omitted to a pressure tunnel. The upper cave is at free surface flow from where the water is going down through my pressure Tunnel to the lower cave system (which is not considered for my case). My plan is to observe the forces induced by the water hammer through closing the outlet. So I would like to use a moving mesh for varying the durations of closing.

So in general I would use interFoam for take the two phases of water and air into account but on the other hand i should use a compressible solver for the calculation of the water hammer effect. For that purpose I would use the SonicLiquidFoam.

Have anyone any idea of how to get both of them together and especially for a kind of beginner in OpenFOAM?

//Edit: I had another look at the solver today and thought about using the compressibleInterDyMFoam. Does anyone have experience with this solver and could validate whether it's a good or a bad choice?

Thanks everyone for helping!

Cheers
