Pressure drop in a nozzle

#1

Can you help me see what’s going on? I’m calculating the pressure drop of a nozzle, and no matter how much I adjust the grid, adjust the relaxation coefficient, adjust the time step, the calculation keeps diverging. I don’t know what other parameters can be modified, please help me, thank you very much!

Please try the attached. I tweaked some meshing parameters and increased the linear solver number of equations.
