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.

Peter

PIMPLE is for Transient state right?
 

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

PIMPLE is for Transient state right?
 

Hi Peter,

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