Hello, everyone, I find a sticky question. I usually use fvMotionSolver or or other dynamic mesh class for mesh motion in my simulations. I found that execution time for every time step increases very quickly with time going on. Therefore, if the mesh is very big and duration for mesh motion is long, main time is spent on latter calculation. But if the simulation is forced to stop and rerun again from the breakpoint, the execution time again increase from a little value.
I attribute the problem to the way of dealing dynamic mesh, so I wonder if any one have ever tried to improve such problems? |
