Hi i try to solve thermal bridge example of Featool
https://www.featool.com/doc/heat_transfer_05_thermal_bridge1#tut_ht05
my heat equation with convection and diffusion
problem heat(u,v) =
int2d(Th)( kappa * (dx(u) * dx(v) + dy(u) * dy(v)))
+ int1d(Th)(Rs * u * v)
- int1d(Th)(Rs * Ts * v);
Rs and Ts are function
func Ts =
+ (0.0)(label==Te)
+ (20.0)(label==Ti)
;
func Rs =
+ (0.11)*(label==Ti)
+ (0.06)*(label==Te)
;
In the tutorial set label isolated
How-to set label are isolated whith freefem++?
