Hi Mahdi,

I was trying to implement the following boundary condition on a wall.

du/dy = B*dA/dx where A is obtained by solving another pde.

I can understand how to implement the boundary...

Hi Mahdi,

I was rechecking the math for the flux BC and it looks like refgrad for region 1 is going to be "q/k1" rather than "q/(k1/(DeltaY1*DeltaY1))". The former looks consistent with respect to...

Thanks Mahdi for the detailed reply. I understood the concept of mixed BC now. However, I am still not sure what is the value that should be specified for T1 or T2. This is because T1 which...
