Hello,



I am writting a UDF code to simulate chemical reaction between phases. However, I can not found information (macro or routine) about to select a specific specie of a phase.


For example:


Species1(phase 1) + Species1(phase 2) ==> Species2(phase 1)



How can I use data specifically from Specie1(phase2) in a UDF??


Thanks.

Domain *domain;
Thread *mixture_thread;
Thread *phase1_thread;
Thread *phase2_thread;

domain = Get_Domain(1)
mixture_thread = Lookup_Thread(domain, zone_id);
phase1_thread = THREAD_SUB_THREAD(mixture_thread,phase1_index);
phase2_thread = THREAD_SUB_THREAD(mixture_thread,phase2_index);
begin_c_loop(c, mixture_thread)    
  {                                                  
C_YI(cell, phase1_thread, specie_index)
C_YI(cell, phase2_thread, specie_index)
  }
end_c_loop(c, c_thread)

Thank you very much for you reply. However, I have another question:



Does it works with Eulerian multiphase model? and if it is, The code is the same?

I want to clarify that this is not a whole code. This is just a procedure to access the mass fraction of specie in a phase. By recalling the phase thread and using Y_CI

The answer to your question is yes, it should work with Euler-Euler model
