I was wondering if anyone has ever attempted to create a dynamic mesh version of the twoPhaseEulerFoam and if so, how successful the attempt was and how involved it is to create a dynamic mesh version of a solver? I was also curious if there might be a more suitable solver present in OF 1.7 for inviscid ship simulations (with a free surface and ship motion)? I ask because although interDyMFoam is a great solver, I don't think a full RANS solution is always the best use of computation resources for all cases. Likewise, if interDyMFoam devolves to a Euler solution when viscosity is set to zero and appropriate BC's, then that would be the preferred method to avoid modifications/developing new solvers if the net effect is still a significant reduction in computation time.

Hi Dave,

Hope you have found a solution. I also need to simulate a moving boundary with multiphase flow inside, so twophaseeulerfoam with dynamic mesh.

Have you successfully implemented this ?

Best regards
