Hello, I could not find enough information about the mesh deformation method used in preCICE. It uses ALE method, but does it use smoothing, mesh regeneration, or elastic model by fem solution? Thanks. ---

Hi Erkhan, if I have understood your question, preCICE relies on how the connected solvers deal with the meshes, It simply passes the information from one solver to the other. For example, in FSI computation, you get the displacements of the structure from the FEM solver and give them to the fluid solver which must deform the mesh. Hopefully this clarifies a bit your doubts. kind regards Claudio ---
