Hello,

to get some experience in Ansys Fluent I simulated a Heatpipe with the VOF method. The water boils and evaporates but there was no condensation in the cold part of the Heatpipe. So I filled the Heatpipe with 100% steam, set the mass transfer from steam to water (evaporation-condensation) and cooled it down but nothing happens. I have no clue and hope you guys can help me.
