I’m trying to simulate an FSI problem using openfoam-calculix adapter. The hydraulic pressure is quite large at first, compared to the structure’s feature. This usually leads to a diverse of the simulation. Is there a way to make it run smoothly?
My idea is to scale the received force with a ratio, for example: force=force0*k, k is gradually approaching 1.0 with time increasing and equals 1.0 after a given time. Does anyone know how to do it? Or if you have other solutions, please give me some suggestions.
