I’m currently trying to couple multiphase solver in OpenFOAM (for the fluid domain) and an in-house code (for the solid domain) to do wave-structure interaction. The main requirement in my simulation is the exchange of the plastic deformation (displacement) and wave impact (pressure) on the interface. After watching several videos and reading threads about preCICE, I think preCICE is quite suitable for my problem but there are still several things I want to confirm:
As stated in one thread, by employing ALE method, “the interface is fixed in the beginning of the simulation (location and number of nodes), but each node gets a displacement that is then used in the calculations”.
Does that mean the values of displacement and pressure exchanged on the interface are obtained from the updated mesh cells? I’m kind of confused as in this video, the slides mention that preCICE maps in reference domain.
As the OpenFOAM adapter has already been developed, I think the main work is to write an adapter for the in-house code. Is there any information for beginners about how to write an adapter? And when using the OpenFOAM adapter, are there any matters needing attention while adopting different slovers in OpenFOAM?
Thanks in advance!
