Pressure diverging problem during LES

I am trying LES with 0.0005s time step,
but pressure is diverging for some time steps. Solution is not always diverging, and divergence occurs about once per 100 time step. I checked velocity field, but velocity didn't divereged and only pressure had diverged to infinite or negative-infinite. I tried LES with other mesh settings with finer meshes, but same problem occurred. Does someone have any idea for reason or solution for this problem? |
