loopbing is on a distinguished road
My case of flow around a cylinder can only run 0.003 time steps, and I want it to complete the 0.3s or even longer. I have tried to reduce the time steps, increase the mesh density, reduce the Courant number, and reduce the relaxation factor, all of which can only comparatively lengthen the running time.
