Hi,

I would like to define a new temperature boundary condition for patches between regions in multi-region solvers.

I have set the target in Make/files as $FOAM_USER_LIBBIN/libuserBCs. and compiled the code. I got the target from the OF's advanced training session manual.

But OpenFOAM complains that the new boundary is not a known patchField type for patch type directMappedWall.

I tried to learn about directMappedWall by looking at compilation instructions for MarshakRadiation, which is one of the allowed fvPatchFields for directMappedWall. It's target is $FOAM_LIBBIN/libradiationModels. I don't see how that is related to directMappedWall.

Thanks,

Mirko

I also tried registering the libuserBCs.so in my ./system/controlDict, but that did not help.

I'm not clear on what is happening. Did your custom boundary condition compile properly? (If not, what was the error?) Then when you ran your solver, what error did you get? The one where it complains it is a generic boundary condition and value() needs to be defined or something like that?

The custom BC solidTemperature compiled properly. When I run the OpenFOAM, I get:

--> FOAM FATAL IO ERROR: 
Unknown patchField type solidTemperature for patch type directMappedWall

Valid patchField types are :

86
(
MarshakRadiation
MarshakRadiationFixedT
advective
alphaSgsJayatillekeWallFunction
alphaSgsWallFunction
...

Thanks,

I found my error. I did not correctly rename all occurances of class names in my files. OpenFOAM is not finding my boundary condition.
