Maximum number of iterations exceeded while doing a rotor 37 simulation

Thomas pan · June 17, 2015, 07:51

I am doing a rotor 37 simulation of a single blade passage with periodic BC using openfoam 2.3.0.I has added SRFModels to sonicFoam,and I get the SRFsonicFoam，it is Compiled successfully.But I'm getting this error(I also has running it with rhoCentralFoam and also using foam-extned 3.1,but the same problem cames):
--> FOAM FATAL ERROR:
Maximum number of iterations exceeded

From function thermo<Thermo, Type>::T(scalar f, scalar T0, scalar (thermo<Thermo, Type>::*F)(const scalar) const, scalar (thermo<Thermo, Type>::*dFdT)(const scalar) const, scalar (thermo<Thermo, Type>::*limit)(const scalar) const) const
in file /home/opencfd/OpenFOAM/OpenFOAM-2.3.0/src/thermophysicalModels/specie/lnInclude/thermoI.H at line 76.

FOAM aborting

Attach Files are my solver,0 files.Can anybody help me....

Hi,
I"m experiencing the same error. Have you been able to fix the problem?

Hi,Franco

I haven't solved the problem.And I change to density based solvers,which works fine.

Thank you very much Thomas. May I ask you which solver are you using now? I'm using chtMultiRegioSimpleFoam.

I'm using transonicMRFDyMFoam in of-extend1.6.It's density based solver ofsimulating the rotating machinery . I don't think it can be sed for you.

I agreee with you. However, thanks again
