Hello Dear Foamers,
I am a newbie to OpenFoam and would like to seek your help to solve an internal flow problem inside a valve.
Its a Steady state turbulent flow and I get the error after 6-8 iterations as quoted below while trying to solve with SimpleFoam.

Foam::error:rintStack(Foam::Ostream&) in "/opt/openfoam222/platforms/linux64GccDPOpt/lib/libOpenFOAM.so"

I hereby attach my fv solution, fv schemes and log files. Any help/guidance is much appreciated.
