Hi,
I am trying to figure out how to solve a temperature conduction problem between two solids using chtMultiRegionFoam. There are no fluids in this problem. My problem is that I don't know how to couple the temperature across the solid boundaries. I have tried using the solidWallMixedTemperatureCoupled, but that does not work Code:
air_to_plate { type solidWallMixedTemperatureCoupled; neighbourFieldName T; K K; value 293.15; } As the problem in the solver that I am using or in the boundary condition? Thanks, Mirko PS - I am attaching the problem files for a simple 2D problem. |

Did you try using the "coupledMatrix" instead? (See conjugateHeatFoam)

Hi Mirko,
Quote:
constant/solid1/polymesh/boundary file: Code:
solid1_to_solid2 { type directMappedWall; nFaces 10; startFace 390; sampleMode nearestPatchFace; sampleRegion solid2; samplePatch solid2_to_solid1; offset (0 0 0); } Code:
solid1_to_solid2 { type solidWallMixedTemperatureCoupled; value uniform 300; neighbourFieldName T; K K; } mad |

Yep, it helped me track down an incorrect entry in the changeDictionary/dictionaryReplacement/boundary/X_to_Y. I had incorrectly set the sampleRegion as X instead of Y. I also used the coupling boundary condition compressible::turbulentTemperatureCoupledBaffle (I don't have a clue why that name. Looking at it's .H file the coupling condition looks very general).

Hi Mirko,
could you post the temperature change in time of some points of your domain and compare them with theoretical time variation? I have some doubts on results I have obtained so far... Thank you mad |

(got busy with paperwork) Unfortunately, I managed to break my two-region problem and loose the temperature connectivity across the interface. FWIW I am attaching two archives:
