Hello，all!
I want to ask how to distinguish DPM injections in UDF programming. I am modeling underwater oil/gas leakage with DPM and I set two injections in DPM for oil and gas respectively.
I write a macro to define gas bubble sizes in DEFINE_EXECUTE_AT_END. Now I want this macro to work only on gas particles when called by FLUENT, i think maybe i can use Get_DPM_injections() to differentiate two injection streams with their respective ID numbers,my question are as follows:
1.for injecioon-0 and injecioon-1 in DPM,are their ID 0 and 1 respectively?
2.Get_DPM_injections(0) or Get_DPM_injections(1), is this usage right or false?

Thank you!
