  I am running a 2d simulation for the adsorption and desorption of particles on activated carbon , I am using a UDF for the adsorption and desorption. The simulation is running perfectly without the UDF but as soon as I interpret the UDF and hook the adjust function and add the source terms and run the simulation, the fluent window crashes with the following error.
  
  "999999: mpt_accept: error: accept failed: No error
  
  ==============================================================================
  
  Node 0: Process 7476: Received signal SIGSEGV.
  
  ==============================================================================
  
  MPI Application rank 0 exited before MPI_Finalize() with status 2
  
  The fl process could not be started.
  
  Also I am uploading the UDF File here :
  
  Thanks for the help, any suggestion will be very much appreciated

  We won't debug the UDF. What you can do first is to start writing some return messages in the UDF to check which part is causing issues. If you are using user vars or cell udmis do no forget to define them first before loading the UDF.
