hi. can you confirm that species in mixture are ordered from 0 , 1, 2, 3 etc.?? Has species in single phase number 0 or "-1"?? And in VOF model primary phase is 2, seconday is 3 and 1 is what? whole mixture?? Than what is 0 if there is?? I know that single and primary phase numbers I can find in phase panel but what abouth the rest I mentioned above? Thank you

The numeration of species in a mixture starts with zero for single phase flows. I can confirm it for species tranpsort model (single phase) and the non premixed combustion model. I had not the time to test it in multiphase but i dont see why it should be different from single phase flows.

The phase index from the phase panel is used in the Get_Domain() macro to get the phase domain pointer. If you use Get_Domain(1) in a multiphase flow you will get the mixture domain. Please note that in this case the "mixture" is the phasemixture and not a species mixture. If you use the Get_Domain() macro to retrieve the phase domain pointer, the zero index is not used.

If you use the DOMAIN_SUB_DOMAIN macro to get the phase domain pointer things are different. In this case the primary phase index is zero, the first secondary phase is 1 and so on (just subtract 2 from the index shown in the phase panel).

Thank you very much
