In this experiment, I present the setup of our first preliminary numerical simulation. The 3" disk was dropped from a 30 cm height, into a water tank of 15x15 cm2. For these #OpenFOAM model, we are using a moving mesh technique (via dynamicMotionSolverFvMesh), instead of overset grids, reducing the computational cost significatively.
The first simulation uses the isoAdvector method introduced by Professor @Roënvy, with the hope of getting the best free surface tracking possible.
The second simulation uses Adaptive Mesh Refinement, through a custom dynamic mesh library and boundary conditions
The source code for all the cases can be found in the following repository:

The compression of the water is close to what happens in a shaped charge
