The Courant number (CFL) exceeded the limit of 1. You may experience either instability or bad temporal accuracy. It is recommended to keep the CFL number below 0.7. In order to achieve this you need to decrease the time step.
Gauge pressure field started diverging. 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.
Gauge pressure = -2.17092e+87 at position: (0.4636 m, 0.7783 m, 0.06533 m).
I am not sure of the âFixed fluxâ for the pressure field. Also, your BC for the top face is not the same! Please at least make it equal and try again.
I have created two seperate volumes one is MFR Zone and a fluid volume. Still the error message dispalys âA multi-region mesh was assigned - this analysis-type requires a single-region mesh.â As this project is for my educational purpose i need to simulate it.
Do take a look at it.
Thank You
Iâd suggest searching for the error message, as oftentimes you will find the relevant documentation very quickly Rotating regions need to be defined as cell zones.
