flux boundary Condition
 

Hi Friends
for my simulation I need to use flux boundary condition as below form:
div(Yi)=Cons(Yi-Yinlet)
this form is similar to convection boundary condition
my questions are :
is there this boundary condition in OpenFOAM?
is there this boundary condition in Groovy B. C. and How to setup this library to my solver?

no body

Use Groovy BC
 

Seek, and ye shall find! And who don't find shall ask.
