Similar boundary condition to zero flux condition
 

Hi Foamers,

I want to implement a zero flux condition as a boundary condition. The equation is:

w*C-K*dC/dz=0

I found different tutorial explaining how to implement a boundary condition. Just below is the best one that I found:

http://www.dicat.unige.it/guerrero/o...plications.pdf

The first step, according to this pdf and many other sources, consists to find a similar boundary condition which already exist.

Does someone have any recommendation about an existing boundary condition similar to the zero flux condition ?

Many thanks,

Xavier
