  Hello all,
  I have been trying to run a fluent simulation with a compiled heterogeneous reaction UDF, I have opened fluent through the VS 2019 command prompt, however, whenever I try to run the calculation I get the following error:
  Does anyone have any idea on how to remedy this, any help would be much appreciated.
  Kind regards,
  Mark

  Hello Mark,
  this error may or may not be related to the UDF. To be sure, have you tried running your setup without the inclusion of the UDF?
  If you have, please ensure that you have correctly compiled and loaded the UDF into your case 5.2. Compiling a UDF Using the GUI (ansys.com).
  Here's a list of compatible compilers for Fluent 2.2. Compiler Requirements for Windows Systems (ansys.com). Alternatively, you may also use Fluent's built-in compiler.

    Hello,
    Thank you for the quick reply, I have run the setup without the UDF and it works fine, I think it is correctly compiled and loaded onto the case but I can't be 100% sure. I have tried using the built-in compiler but it gives a very similar error with just one bad termination message, followed by the program crashing.
