Calculated BC

Hi,

J was defined here as function of the field "c".

and
i need to solve the "c" volscalarMatrix eqn
lets say:
solve
(
fvm::ddt(c) + fvm::div(phi,c) == fvc:: (A*fvc::div(J) )
)

the question is
How to put a BC on a patch for "c" field, that depends on "J"

forExample, i need to put J=0 in a certain patch of the "c" Boundaries.

Thanks a lot

T.D.

Do you have an answer?

I cannot find any example of how to use "calculated" boundary condition. I even don't know if it's a correct choice.
