Internal boundary conditions for diffusion equation
Hi All, I'm modeling simple diffusion in a 2D geometry; however, the geometry contains some internal boundaries that I would, at times, like to be able to represent as walls. Consequently, I need to...

Hey, I think the best way to do this is to turn off 'active in this domain' for the adjacent subdomain. This will make the internal boundary effectively become an external boundary. If you need to...

Hi Adam, That's a good idea, but unfortunately, the internal boundaries do not subdivide the domain, so there is only one domain. I can solve the problem by making the internal boundary an external one...

Hi, I'd suggest the idea shown in the model linked to at the bottom of this entry. The concept is pretty general, so I will outline it here. Some boundary conditions are available only on exterior...

Thanks Linus, that does solve the problem I'm trying to solve! -joe

may i get that file which shows how to use insulation at internal boundaries ? please help.

Hi these files are only awailable a short time, but the explanations of Linus are straightforward. use an assembly mode and link part of the dedoubled boundary as continuity, another part with your...

Hi Linus: I am just wondering if you could send the example zip file again. I was trying to follow your description but still cannot achieve the interior boundary conditions in COMSOL. I know it has...
