How to define function for material properties in CFX?

Hamda · July 28, 2018, 11:27

Hi,
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

Have you done the tutorial examples? I am sure some of those will show how to set up materials. They are available on the ANSYS Customer page (and the ANSYS Academic page for students).

Defining material properties as functions of temperature is just a CEL expression. Again, refer to the tutorial examples.

Thank you for your response.

I have already known what to do..I watched a video that was so helpful and gave me some insight into CFX.

By the way I should confess you are a useful member of this forum.
Thanks,
Hamda
