SubscriberHello,Â
I've been trying to get a *.mat file of nitrogen and helium to calculate mixtures
This archive should look like this:
Property   Value   Unit
Medium: Â Â helium
Pressure: Â Â 50 Â Â [ bar ]
Temperature: Â Â 526.85 Â Â [ Celsius ]
Density: Â Â 3.026 Â Â [ kg/m3 ]
Specific Enthalpy: Â Â 4185.000 Â Â [ kJ/kg ]
Specific Entropy: Â Â 28.38000 Â Â [ kJ/kg K ]
Specific isobar heat capacity cp: Â Â 5.191000 Â Â [ kJ/kg K ]
Specific isochor heat capacity cv: Â Â 3.122000 Â Â [ kJ/kg K ]
Isobar coefficient of thermal expansion: Â Â 1.240000 Â Â [ 106 Pa s m-1 ]
Heat conductance: Â Â 308.0000 Â Â [ 10-3 (W / m * K)]
Dynamic viscosity: Â Â 39.50000 Â Â [ 10-6 (Pa s) ]
Kinematic viscosity: Â Â 13.0535360211 Â Â [ 10-6 m2 / s ]
Thermal diffusivity: Â Â 196.0000 Â Â [ 10-7 m2 / s ]
Prandtl-Number: Â Â 0.665
Coefficient of compressibility z: Â Â 1
speed of sound: Â Â 1675.000 Â Â [ m / s ]
Do you have any idea how to create properly this file or how to obtain from ansys? -

Forum ModeratorIsn't there a file definition in Matlab's Help? I'd be a little surprised if any of the Ansys tools linked up directly, although some of the Materials tools might.Â

SubscriberAnd for python? Or there's any other solver to work directly?

Forum ModeratorWe have a material database of some form in most of the solvers, and also functions in the Granta tools. The latter typically don't have fluids and the former are designed for use in the specific solver. You can export material libraries or properties, but possibly not for Matlab as it's not an Ansys product.Â
