Get species index at two different phases in VOF
 
Hi,

I am using VOF multiphase model to simualte multiphase heterogeneous chemical reactions. In UDF DEFINE_VR_RATE function, how can i get species index at two different phases?

For example, gas phase, pure substance: H2

liquid phase, mixture: methanol, chemical A, chemical B

heterogeneous reaction: H2+A=B In UDF, how to get yi[h2] in the gas phase and yi[A] in the liquid phase?

Thanks for help.
