Hi, I'm using rhoTurbFoam to s
Hi, I'm using rhoTurbFoam to solve for supersonic flow. The solver works fine for mach number 1.0, but i get the error message that the max number of iterations is reached verytime i do something more than mach 1.0. I've attached the error message below.

Hia Jia,
do you found the tri
Hia Jia,
do you found the trick? I faced this error in dieselFoam, regards, Hamed |
Hi,
I am also getting this
Hi,
I am also getting this message when running rhoCentralFoam. My case has both subsonic and supersonic flow and seems to work fine but then always crashes with this error after a while. Does any one know what it means? Thanks Kieran |
Same Err
Hi..friends.
I am solving one case using rhoTurbFoam but after few iteration it stops with the same error report as mentioned above. I am not getting why this Err means. What I understood is there may be sudden Temp raise found this is causing Err. I am not sure. I tried to verify BCs and discretization schemes also but got no idea about Err cause. Pls..come forward and help to understand it. Thanks Mehulkumar |

hello friends,
i am facing some issues after 2 iter, please find attached log file Maximum number of iteration exceeded#0 Foam ::error::printStack(Foam::Ostream&) error. please help me any body, i found error after 2 iterations |
hi..jia_kok
Did you fix that issue? if it how did you do it? i am facing same problem, please help me on the same |
MOst probably your BC are wrong.
Look at rho ! Its too high ! That is leading to problem with time step continuity... recheck your BC and how do you initialize your domain? |
