Hi, I'm trying to solve the compressible Euler equations in Lagrangian coordinate with two fluids separated by a free surface. They are no mixing between the two fluids. The mesh is moving with the fluids and the quality of the mesh degrade rapidly with the deformation. So I need tools to correct the mesh, just like your AMR tools and your VariationalSmoother functions. But I have to know if the AMR and the VariationalSmoother support the presence of internal boundary (a free surface) and how they deal with it.
So I have two main questions: 1- Is it possible to add a free surface (or an internal boundary) in a mesh? If yes, how can I add a free surface in libMesh? 2- If I suppose that I have an internal boundary in the mesh and I use the VariationnalSmoother and the AMR. What happen to my internal boundary? Is it preserved or the algorithms with destroy it or move it.
