Hello everyone,

I wanted to simulate a water thermosyphon (a long tube filled partially with water) startup. I wanted to heat the wall of the thermosyphon with a heater with a certain power (for example 40 W). I tried to model it in openfoam-2312 using interCondensatingEvaporatingFoam solver with externalWallHeatFluxTemperature Boundary conditions but I got this message instead,

--> FOAM FATAL IO ERROR: (openfoam-2312 patch=240220)
Unknown patchField type externalWallHeatFluxTemperature for patch type wall

I guess it's not available for this solver, are there any way I can add this manually?

Thank you,

Best,
Almanzo.
