. Why is my plot flattering and not converging. Is this plot normal? I am doing CFD of the pump.

Hey there, welcome to the forum!

I just checked your project and couldn’t find this residual plots. I guess you already improved your setup.

Here are some suggestions for you to improve the model:

  • Extend the outlet face several diameters of length to create a pipe.
  • Extend the inlet also.

Thanks for the reply, i will try it.
