Hi, Tanmoy

Thanks! Here are parts of my logfile, and please see the attachment for details. (I didn't change any data for this case)

Hi Hu,


Please post a MWE (minimal working example), a logfile / and or a .usr file snippet which your are changing, otherwise it is hard to comment.



Best Regards,

Tanmoy

Hi all,
When I tried to do the test "turbChannel", I found value NAN appeared in the process, and after a while the pressure solver detect rank deficiency. I tried almost all the
test case, and found this problem appeared in some other cases. I want to know why and how to accomplish the turbChannel case. Should I change any values in the .usr file?

Best wishes!
Hu
