UDS Diffusion Coefficients

      Hello,


      I have problems with the UDS option. It would have to have the coefficients (kg/m-s) and not the ones it currently has.


      Can somebody help me?


      Greetings and thanks

      Scalars don't have a density so you need to account for that in the maths: there is something in the manual, but no one ever notices unless they're using expressions.

      Thanks for your reply Bob.

      I must write a constant. The problem is that later, in the materials menu, it does not appear in that option.

      You did turn scalars on and set them for the correct zone types?

      Hello Rob
      I have this menu.

      OK, so Scalar-0 is set for the solid zones. What about Scalar-1 ?

      Improper arguments start checking the material properties and whether every input is filled with correct input.
