Steady state conjugate heat transfer analysis in openfoam version 7

Hello,
I am using openfoam version 7 and i want to run a steady-state Conjugate Heat transfer analysis. In openfoam version 7 there is no slover like "chtMultiRegionSimpleFoam". They are clubbed. from openFoam v7 documentation: chtMultiRegionFoam Solver for steady or transient fluid flow and solid heat conduction, with conjugate heat transfer between regions, buoyancy effects, turbulence, reactions and radiation modelling. So i ran my case with the command chtMultiRegionFoam. I am getting the error: --> FOAM FATAL IO ERROR: keyword PIMPLE is undefined in dictionary "/home/kpit/OpenFOAM/kpit-7/run/tutorials/heatTransfer/chtMultiRegionFoam/PFC_half_plate/system/fluid/fvSolution" file: /home/kpit/OpenFOAM/kpit-7/run/tutorials/heatTransfer/chtMultiRegionFoam/PFC_half_plate/system/fluid/fvSolution from line 22 to line 56. From function const Foam::dictionary& Foam::dictionary::subDict(const Foam::word&) const in file db/dictionary/dictionary.C at line 708. FOAM exiting i used SIMPLE as my algorithm since its steady state. Can anyone help? |

Just replace:
ddtSchemes { default Euler; } with: ddtSchemes { default steadyState; } in: fvSchemes for all regions! And replace SIMPLE with PIMPLE in fvSolution for all regions. Regards Peter |

PIMPLE is for Transient state right?

PIMPLE is used for transient solver right? so how can we use it for steady-state?

Thanks for replying. But PIMPLE is used for transient solutions right? |
