Hi all,

I'm working on solving a case in rhoCentralFoam and keep getting a "Maximum number of iterations exceeded" error after a handful of iterations. I used snappyHexMesh to generate the mesh, and am running the case in parallel. I'm new to openfoam and cant really make much of the error, or where the source of the error is located. I've attached the log file with the error below. Any help would be appreciated!

Thanks,

Basically, you blew up the thermo solver (the iterations to solve for thermodynamic parameters could not converge accurate solution due to poor input) . This is most likely directly due to negative temperature and/or pressure. Try running the case in serial if you can or printing out every timestep to see where error occurs. The problem is likely in your mesh or boundary conditions.

Thanks for the advice - I recently found the error: I was stupid and put cp in units of kJ/Kg K instead of J/kg K, and that being off by a factor of 1000 is what blew up the case.
