Concentration dependent source/sink

    • zdfrankman

      I am trying to model cells in a channel consuming oxygen from a bulk flow of water.

      I am employing the Species Transport model and have a "Cells zone" that has a negative source term to model the consumption of oxygen by the cells. 

      I would like to have the negative rate term be concentration dependent - that is to say, instead of the consumption rate being "-1" I would like it to be "-1 * Oxygen concentration."


      How can this be done without using a User Defined Function?
