phase_index

grzes

hi, Can you help me to determine a phases and species numbers? I have two phases: let say liquid water and water vapour. What are the numbers of phases in phase panel and what will be a numbere of phases in UDF listed below:

DEFINE_MASS_TRANSFER(dml_v,cell,thread,from_phase_ index,from_species_index,to_phase_index,to_species _index) { .............

from_phase_index=?????; from_species_index=?????; to_phase_index=?????; to_species_index=?????;

in my case primary phase is water vapour and secondary phase is liquid.

thank you for help
