30N30P_MultiElement_Airfoil

[hosshvsi]

Hello everyone,
I just wanted to run the multi element airfoil tutorial, I installed v3.1.1 and then mount it
after couple of seconds, I faced with error message. It was wired because I didn't change anything (mesh setup or running script).
would you please help me in case to address the issue?

I just ran the case without a problem. Did you run Allclean.sh before running the case?

[hosshvsi]

yes, I did
after reaching 2,000 iterations, apparently, I will be facing with an error regarding Primal Residual:

Primal min residual 2.749081039355476e-06
did not satisfy the prescribed tolerance 1e-08
Primal solution failed!

to address that issue, I increased the number of iterations in controlDict to 10,000 and also decrease Primal Residual from 1e-8 into 1e-6, then it was working but after 2 hours this error which I attached shows up.

Im suing v.3.1.2 first ./preProcessing.sh and then mpirun -np 4 python runScript.py

The case finished successfully. The "error" you mentioned is a warning.
