      It's not quite that easy at the moment. If you turn on species there's a specified value (from memory) but it's often that we'd use a source term into the near wall cell. There's an enhancement request in for the feature, but I have no knowledge as to when it'll happen.

      You can refer to Section “ Species Boundary Conditions for Walls” in the Ansys User Guide for more infromation.
