  I am trying to simulate reactive flows in porous media (catalyst). I use UDFs for reaction rates. I tried using interpreted UDFs. I get this error:
  Error: C:/Users/chanda/AppData/Local/Temp/PandyaKinetics.C.28788.3.c: line 73: structure reference not implemented
  Do I need to get compilers for ANSYS FLUENT?
  Can someone please help me with the error and C Compilers installation for ANSYS FLUENT?
  Thank you so much

  In Fluent there's a built in compiler, that takes away all of the pain associated with getting Microsoft VS to work (assuming you can find all the components).

  Thank you Rob. I am using FLUENT 2021 R2. Does this version have built-in compiler?
  Thank you.

  Yes, it's in the Compiled UDFs panel, look for the tick box. Just don't use that option on Linux!
