Hi,
I have a three dimensional geometry with different subdomains. To implement my weak form including the region boundaries, I was following the approach recommended in
this thread
.
My confusion now is that the indicator function is not acting as expected since it is indicating some sides of the domain (see the attached example adapted from the tutorials). I checked the current tutorials and the difference from the working examples appears to be that this is a three dimensional mesh. I'm not sure if I have to adapt my example somehow or if the CoefficientFunction does not have this information like it doesn't have the boundary region information?
I also tried setting GridFunctions as a workaround but these are interpolating into neighboring subdomains -- maybe there is a way to prevent this?
Please let me know and thanks in advance,
Josie
