Hey all,


i always use a constant wall temperature to create my bc condition.

so the question is if i can use a constant wall heat flux like that way:

file T

hot_wall
{
type constantWallHeatFlux;
heatFlux uniform 23; // [W]
}


best regards
Tobi

Specifying a fixedGradient should be equivalent to a heat flux. You just need the proper scaling:

q = k * grad(T) <-> grad(T) = q/k;
