What is T_g? Have a look at the "mixed" boundary condition, or otherwise groovyBC, which is built on that boundary condition.

hello,
You also may take a look at the "externalWallHeatFluxTemperature" boundary condition, which does what you want. regards, olivier |

hello,
About the externalWall... bc, this depend of your solver. For a wall, try the banana bc, you will get an error with all possible bc. If externalWal... is not here, then go with swak. regards, olivier |
