I am getting this message on running my simulation. “Gauge pressure field started diverging to a value of 4.66023e+16 Pa near the position: [(3.173e-4, -1.199e-1, 4.014e-5)](https://www.simscale.com/workbench/?pid=9176008974109573608&mi=run:15%2Csimulation:8&mt=SIMULATION_RUN#). Please check the mesh quality near the reported location and try refining the mesh. If the problem occured near a boundary, please check the boundary conditions. In case of doubt, please ask for assistance via our support chat.”

please help me in this

With me it helps sometimes to reduce the URF values… And perhaps add initialisation values.
