  Hello everyone,
  
  I get an error when I apply the macro F_YI(f,t, i) AND F_R(f,t) in the PROFILE_DEFINE macro. I keep crashing when running the model with this macro. Can you give me some advice about this situation?
  I previously tried the method of doing it using DEFINE_ADJUST and got the same error
  
  My goal is the macro application to manipulate species production in "species transport" at wall boundary conditions. (time: transient; viscous: laminar; material mixture; Scheme PISO, Pressure: presto; transient formula: second order)
  
  thanks and best regard
