I am running a test pump station model, which crashes after running for a while. I have used volume flow rate both in the inlets and outlets. I tried using different mesh refinements and smaller time steps but couldn't figure out how to fix the problem. I am also attaching the checkMesh.out along with the model files. I have just found "If you specify velocity/flow rate at the inlet/outlet, you should specify pressure at the outlet/inlet." Is it possible to use pressure in the inlet and flow at the outlet? I highly appreciate your help.

You will find the model files at: https://dsllctn-my.sharepoint.com/:u...PguLA?e=IKxTqi

I have ran another model of the same pump intake station where I used pressureInletOutletVelocity for the inlets and flowRateOutletVelocity for the outlets. This model also crashed after running 17s with similar error message. Here is the link of the model files: https://dsllctn-my.sharepoint.com/:u...OZXRQfoCvznmDw

I highly appreciate with any insight. Thanks.
