Hello everyone, newbie here.

I have a basic fluent solver doubt. For setting up evaporation for a chemical species, Saturation Vapor Pressure for that species is needed to be specified in Material Properties for the solver to calculate mass exchange. Is the pressure specified, Gauge Pressure or Absolute Pressure?

Please help me as my solution is changing a lot, considering that I take it as gauge/absolute pressure. I have already checked Fluent Manuals and other posts on this forum, but it is still not clear.

Thanks a lot in advance.
