Dear all,

I am completely new to OpenFoam. I am working with a simple case of heat transfer (chtMultiRegionSimpleFoam) between 2 solids on OpenFOAM v.2.1.

As far as I understand, I am having trouble applying boundary condition.
This is the following message that appears to me:

Time = 1


Solving for solid region leftSolid


--> FOAM FATAL ERROR:
Attempt to cast type calculated to type compressible::turbulentTemperatureCoupledBaffleMix ed

From function refCast<To>(From&)
in file /home/paula/OpenFOAM/OpenFOAM-2.1.x/src/OpenFOAM/lnInclude/typeInfo.H at line 114.




I would be very grateful if anyone could guide and tell me what I am doing wrong.

Best Regards

Paula

Hi Paula,

What this error message is saying :

1. In your ~/constant/polymesh/boundary file (boundary condition's type), you have defined a boundary as a a coupled wall (compressible::turbulentTemperatureCoupledBaffleMi xed)
2. In one of your ~/0/* files (definition of the boundary condition's values), you have defined the same wall as "calculated".
3. OpenFOAM is telling you that those 2 are not compatible.

You should upload your case folder, it would be easier to help your further.

Hi,

this should be easy to fix. The 'T'-file in the 0 directory for the leftSolid is set up properly (with turbulentTemperatureCoupledBaffleMixed), whereas the T file of your rightSolid contains the keyword 'calculated' for the coupled wall patch. Change this entry to compressible::turbulentTemperatureCoupledBaffleMix ed (according to your other T-file) and everything should work.
