How to define BC for internal layers

kamran46

Hi all,

I am new to this forum and COMSOL. I want to define the temperature at the common surface of two cylinders in contact. When I model the cylinders, the common surface (middle surface) is not active for defining any BC. Please tell me how can I do this in COMSOL. Thanks.

GT1

go to Physics->Boundary setting->mark the interior boundaries checkbox.
and then you can set BC.

Thank you very much.
