There is a "Multi-Component" model in CFX for the mixture simulation.

And cfx also has a 'free surface' model which is one of the multi-phase model.

Actually I also want to simulate a multi-component model with free surface, however, it seems that cfx is not able to deal with the 'mass fraction' in multicomponent and 'volume fraction' in multiphase appropriately. I still don't know how solve this problem now.

Does anybody have more information regarding this problem?

what material do you use?

Is that a multi-component material? or a PURE material?

If a pure material, the cfx works appropriately.
