Referring to Comsol 4.4 Manual, under equation-based modelling, general form PDE pg762, what exactly does line 3 and 4 in equation 16.1 mean ?
I am simulating joule heating physics on a simple geometry(rectangular box). I have defined heat flux on one of the boundary/surface with qo=500 W/m^2.
I would like to know if general constraint BC, (R=0 line 3 in eqn 16.1) is really being used in heat transfer interface. Is R=0 everytime?
Could anyone explain how these constraint and Dirichlet bc in equation are being used?
Many Thanks.
