Wall Surface Reaction Problem with UDF

      Hello Everyone,

      I am trying to simulate the flow of gaseous mixture in the channel. walls of the channel are catalytic and wall surface reactions are happening. I wrote a UDF for surface reaction rate and successfully compiled and its showing in function hooks. geometry of problem is shown below.

      Hello,
      Can you please make sure that the UDF is compiled right? You also might want to check where the reaction mechanism is being pulled while solving. You can plot a contour of, say, species and check if it makes sense.

      Hi RK UDF is successfully compiled without any warnings and errors and its hooked properly, I defined the species in orders and reactions in the mixture template panel same as my UDF, but still not getting my reaction rate.
      I had given random rate exponent in mixture template panel (all is equal to 1), because I think it will take directly from the UDF. Is this correct ?
