How to visualize Output Equation Residuals in CFD Post

rubin4ik · June 22, 2011, 03:13

Hi,

I would like to visualize the output equation residuals in CFD Post. I checked the relevant Box in CFD Pre.
My problem is how to access this variable in CFD Post, because I can´t find it in Variables or anywhere else!

Thanks a lot for your support!

did you finish the run and write a full .res file? in that case, the residuals should appear as variables ("U Mom.Residual" and so on ...)

if you only wrote backups:
- automatic backups only write the residuals if they are specified in pre as well (as you did with the normal output residuals).
- manual backups ignore all settings and don't write residuals. if you want them to include them here, you'll have to set the expert parameter "output eq residuals = 1" first (can be done during the run) and then do the backup.

hope this helps
