Default Additional variable - wall boundary condition
Posts: n/a

I have defined a additional variable, and I have defined fixed values for it in the inlets and outlets (in case of recirculation occurs).

What I couldn't do is to define a fixed value for my additional variable at the wall boundary conditions. In the CFX manual is written that it is possible, and that it works in the same way as the heat transfer boundary conditions, but I haven't found a way to set it up in CFX.

Any help will be appreciated.

Dear flga,

If you set the Kinematic Diffusivity for your Additional Variable, then you can specify the wall value. Otherwise, the value at the wall is irrelevant since it cannot diffuse.

Hope it helps,
