Hi:

I am a Fidap beginner and working on a project using fidap right now. In the project I have to apply a mixed boundary condition, not sure if Fidap subroutine is able to handle it. Here is the BC I am gonna choose:

U*C+Coef1*(dC/dn)=Coef2*C

where U,C are velocity and concentration on the boundary respectively. dC/dn is the first derivative of concentration with respect to normal direction. Coef1 and Coef2 are two constants.

Thanks with advance.

Ning
