    It is possible to create Material models in AcuConsole (for AcuSolve). If there are non-constant properties they can be imported using CSV files..

    Yes, there are non-costant properties. How can I import these properties and how shoud I write them in a CSV file? For example, I need: density = f (T, p)

    Have you tried importing a text file (or CSV). Go to AcuConole > Tools > Material Models > Import

    e.g

    273   1

    300   1.1

    323   1.2

    Thank you for your answer, ydigit.

     
    Assuming that I can import a three-column csv file (pressure, temperature, density), How does aAcuConsole know that the first column represents temperature, etc...?

    If your property needs to be a function of two different variables, you'll need to use a user function.  AcuSolve does have pre-defined isentropic and ideal gas density available, which may be what you need.  The Command Reference Manual will have an example user function in the material model (or density model) section.
