Boundary conditions for weak or general form PDE

Please login with a confirmed email address before reporting spam

Hello,

I need to solve a system of two coupled second order elliptic PDEs for quantities u and v; there are no boundary conditions imposed on v, but both u and the normal component of the gradient of u are specified on the boundary. How do I impose these boundary conditions in COMSOL using either weak or general form PDE? Thank you.

Dmitry

Have a look at Dirichlet and Flux/Source boundary conditions.
