Mass Concentration
 

Hi,everybody. I'm now doing a simple case of fluid(variable component material) flowing through a duct. The fluid is consisted of 7 gas components. In CFX-Post, I couldn't examine the "Mass Concentration" of each component at a certain self-created location, since "Mass Concentration" was not in the variable list. Anyone could tell me how to display the "Mass Concentration" result? Thanks very much!
