Hello dear people,

I am tryning to impose a mass flux boundary condition to a wall boundary. Fluent provides only zero mass flux. How can i change that? Is there a way?

Thanks in advance.

Fluent have other BC's that satisfy your requirement for outflow or inflow. However if your concern is about using porous media then refer to Fluent for extra information.

Good luck

The BC is not an inlfow or an outflow. It's in a wall. That's my problem. Fluent has only zero diffusion flux.
