Oscillating OMEGA residuals

Project Support
1

Hi there,

I have a small issue with my residual results, especially with the OMEGA term and slightly with the k term. As seen in the image the OMEGA suffers oscillation issues, my questions are

  1. Does this cause inaccuracies with results?

  2. How can i prevent these oscillation occurring?

Hi!

This looks like numerical artifacts, but nothing serious to me.

I would allow this simulation to run for more iterations for the solver to drive down the residuals.

Hi there, thank you. I will run the model for longer now and post the results.
