Spalart Allmaras nan error
I am running a case of injection and suction on the surface of the aerofoil using the Spalart Allmaras model. Mass flow inlet and pressure outlet gauge pressure is set to 0.
I get this error after about 2000 iterations.
"Error: > (greater-than): invalid argument : wrong type [not a number] Error Object: nan"
May I know what is the problem?
Previously I ran a case with inlet gauge pressure of 500Pa, and outlet of 0Pa and there is no such problem.
these are the last 3 iterations before the error.

none of them is approaching 0, so why is there such an error?
appreciate if someone could help. thank you.
can anyone help?
