Coupled Boundary conditions

Please login with a confirmed email address before reporting spam

Hi,

I am very new to Comsol! My equations are the following:


dc/dt=D*(d^2c/dy^2)

BC
t=0 c=0
y=0 D*(dc/dy)=k1*(c0-c)
y=h1 D*(dc/dy)=k2*(cb-c)
coupled to ...
dcb/dt=k2*(cb-c)/h2;

constants h2, c0, k1, k2, D
Please help me on how to feed this boundary condition to COMSOL ?
