Hi, All!

I'm writing a boundary condition, where I want to get values from a patch from another region. Basically, my boundary condition will calculate gradient for 'fixedGradient' based on the field values on the two patches, which aren't in contact (there's another region in between).

Please, any ideas on how I could do this?

Best wishes,
Ilya

Hello Ilya,

did you make any progress in accessing a patch within a different region?

I'm currently facing a similar problem in chtMultiRegionFoam, where I want to access a boundary in the solid region from a fluid boundary.
