hi
i'm trying to solve an openfoam 1.6 case with openfoam 2.1.0.i have been changed every file of this case to compatible with version 2.1.0...finally i could run, but this error appears:
--> FOAM FATAL ERROR:
Maximum number of iterations exceeded

From function specieThermo<Thermo>::T(scalar f, scalar T0, scalar (specieThermo<Thermo>::*F)(const scalar) const, scalar (specieThermo<Thermo>::*dFdT)(const scalar) const) const
in file /home/opencfd/OpenFOAM/OpenFOAM-2.1.0/src/thermophysicalModels/specie/lnInclude/specieThermoI.H at line 69.

this is the original fvsolution file in version 1.6:



solvers
{
rho ICCG 1e-06 0;
U BICCG 1e-06 0;
p ICCG 1e-09 0;
Yi BICCG 1e-06 0;
h BICCG 1e-06 0;
k BICCG 1e-06 0;
epsilon BICCG 1e-06 0;
}

PISO
{
nCorrectors 2;
nNonOrthogonalCorrectors 0;
}


and this is the fvsolution file that i changed it:


solvers
{
rho ICCG 1e-06 0;
U
{
solver PBiCG;
preconditioner DILU;
tolerance 1e-06;
relTol 0;
}
p ICCG 1e-09 0;
Yi BICCG 1e-06 0;
h BICCG 1e-06 0;
k BICCG 1e-06 0;
epsilon BICCG 1e-06 0;
UFinal
{
$U;
}
}

PIMPLE
{
nCorrectors 2;
nNonOrthogonalCorrectors 0;
}
how can i fix it?
thank u all
