Hello CFX-users !

I've been throught the help and the forums, and I can't find how to enter the material properties knowing that I want to simulate phase change of Magnesium gas into solid particles ...

Do I have to enter only one material at normal T and P conditions ?
Or a solid material at normal T and P conditions and gas material at higher temperature conditions ?

I am currently using nasa format for the Cp implying that it changes with temperature instead of entering a value.

Thank you and good afternoon !

Romain

Modelling phase change is complex. Before you look at your magnesium case, do you thoroughly understand phase change on a well studied case like water? Make sure you understand phase change in water thoroughly before starting anything else.

Hello Glenn, and thank you for the answer.
I don't know about water phase change, or just a little as I read some threads and CFX help.
Anyway is there any specific tutorial about this cas ? Because the ones I found aren't really exhaustive ...

There are more tutorial examples on the ANSYS community webpage. Also ask ANSYS support for examples of the sort of phase change you want to model. They won't have much for magnesium but they will for water.
