After extensive research into chtMultiRegionFoam I am yet to get temperature to cross a boundary between solids or fluids. I have looked at all of the cfd forum posts about it and looked extensively at the tutorials. I have attached my folders and a screenshot of paraveiw showing me the solution, which does not change with time (for a minuet). All I want to do is get tempreture flow from a solid/fluid to a solid/fluid, my geometry is essentially a tower block starting with 2 solid sections then a fluid section then back to a solid section numbers form 1 to 4. This is exactly what I have done after setting up the folders appropriately:

fluentMeshToFoam constant/polyFoam/thermo9FL.msh -writeSets
setsToZones -noFlipMap
splitMeshRegions -cellZones -overwrite

Then delete all 0/region/files that are not applicable to solids/fluids.

ChangeConditions (a bash file I wrote to run changeDictionary for all regions in turn)

Then I renamed all *Zones by adding .bak

StitchMeshes (another bash file that runs stitchMesh -overwrite -perfect on all internal walls)

Then remove the new cellZones and remove the .bak from the old one
Then delete all boundary's with 0 in nFaces in constant/polyMesh/boundarys

checkMesh (says its ok)

Then change all boundary's in constant/region/polyMesh/boundarys to mappedwall for the internal walls to match the 0 condition of compressible::turbulentTemperatureCoupledBaffleMix ed that is set up.

Then move meshPhi form the 0 folder to 0/topRegionInTheFolder (otherwise I get an error)



Additionally: why does there need to be a small velocity passing though a fluid to make the fluid allow heat to flow from one of its boundary's e.g. use 'fixedValue' and set a wall surrounding a fluid to 500K, it only heats up the fluid if there is a small velocity running though it. I have the same problem with a solid however have no solution to make the heat move throughout it.

I am currently using OpenFOAM V2.1

NOTE: I had to upload the constant folder separately and had to delete some of its files so it would upload (eg faces, the mesh, sets, ...)
