weak form boundary application

Hello everyone,

I 'm using comsol V3.5a

I would like to impose (on a wire surface) a Dirichlet boundary condition rho=rho_wire (space charge density).
For this, I must use Point Equation for rho_wire using PDE weak form (boundary application).

How I must make so that rho_wire becomes a Lagrange Multiplier that is used to impose on the wire the potential boundary condition : phi=phi_wire ?.

Best regards,

Have you got any solution to your problem? I am also having a problem regarding the weak form boundary application.
