Hello Mohammad, >From the error message, the job was terminated for exceeding time limit, meaning the job is still running, it just takes a very long time. From the output message, the FSI solver did not get initialized either. Your FSI parameters look good to me
Without running your simulation, I think it's likely that something is wrong with CreateMeshPoints(), which is for generating BCE markers that describe the screw geometry. Since decreasing resolution will take longer time to generate the markers, the program could still be computing the markers. The implementation right now doesn't scale well with higher resolution. It might also got stuck in some infinite loop ... I will need the screw geometry to look into this more. You can also generate the BCE markers yourself, and read the points in the FSI program, then attach them to the screw body using AddPointsBCE(). That way you have control over how to place the grid points so it can capture the geometry. You can also speed up the process by parallelize your implementation. You only need to do it once.
