I am pretty new in CFX and I don't know how I can define material properties in CFX. this is not like FLUENT at all! for example in the material library , there are just air and water! and should be imported material . in my project, fluid is Helium and in CFX , there is He at STP? what does it mean ?
Also how can I define helium properties including conductivity, density ,...as a function of T?
Many thanks in advance
