Condensation
 

Hi.

I am trying to simulate condensation of air-vapor mixture in a tube. I am using a rpg file for material properties of steam. This gives a global error in cfx-pre " The molar mass needs to be set for multicomponent cases". In rpg file molar mass of steam is not defined and there is no any option to enter the value in material window. I tried to edit the rgp file but that didn't work. Please help me to fix this problem.

Thanks

Sameer
