My solver offers adaptive mesh refinement.
Can I use this with preCICE?
Please also ask: “Is it correct that preCICE cannot support couplings when the interface mesh is changing its connectivity during the simulation?”
Currently, the mapping setup only occurs once during the initialization of preCICE. Thus, in order to modify the mesh and therewith the mapping one must restart the simulation. It depends on a case-by-case basis whether this costly method is acceptable or not. A dissertation in progress studies dynamically changing coupling meshes, such that preCICE will be able to handle adaptive meshes in the future.
