After I modified our in-house code using preCICE with my colleague, I’ve been trying to do some FSI simulations using OpenFOAM and our in-house solver. For a simple flap case(100 cells for solid part and 50000 cells for fluid part), the mapping process is pretty fast and the simulation finished successfully.
However, for another simple simulation similar to the turek-hron-fsi case(1600 cells for solid part and 20000 cells for fluid part, my .xml file is uploaded.), both participants calculate really fast, but the mapping data process takes about 10 to 20 seconds. Why does mapping data take so much time?
Since our aim is to do large scale simulation, such time cost in mapping data is unacceptable. Is there any methods to speed up the mapping process? Could it be done in parallel? Any comments will be appreciated!
