 May 18, 2006, 04:04 About create new material #1 jasonchang Guest   Posts: n/a When i simulate fluid flow,I do it succesfully by use water as the material,but use a material created by myself, Error ,as below: | ERROR #001100279 has occurred in subroutine ErrAction. | | Message: | | NAME_MOD: Error finding variable "DRHODP_T" The material I create as follow: LIBRARY: MATERIAL: Aluminium Liquid Coord Frame = Coord 0 Material Description = Aluminium Liqid is used for foundry simulation Material Group = Constant Property Liquids Option = Pure Substance Thermodynamic State = Liquid PROPERTIES: Option = General Material DYNAMIC VISCOSITY: Dynamic Viscosity = 0.0012[Pa s] Option = Value END EQUATION OF STATE: Density = 2.371 [g cm^-3] Molar Mass = 27 [kg kmol^-1] Option = Value END SPECIFIC HEAT CAPACITY: Option = Value Reference Pressure = 1 [atm] Reference Temperature = 700 [C] Specific Heat Capacity = 950 [J g^-1 K^-1] Specific Heat Type = Constant Volume END THERMAL CONDUCTIVITY: Option = Value Thermal Conductivity = 217.7 [W m^-1 K^-1] END END END END Help me!Thank you in advance!

 May 18, 2006, 08:22 Re: About create new material #2 chayriss Guest   Posts: n/a Dear jasong, I think this is not a ""Material Group = Constant Property Liquids""" you can try with Material Group = user , that is the first mixtake i see, I not sure, but I hoppe this can help you best regards chayriss

 May 18, 2006, 09:30 Re: About create new material #3 opaque Guest   Posts: n/a Dear Jason, I notice that you are setting the Specific Heat Capacity at Constant Volume instead of at constant pressure.. To convert from Constant Volume to Constant Pressure you need the derivative of density respect to pressure at constant temperature.. Perhaps the conversion has a bug.. Try setting the Cp instead.. Good luck, Opaque..

 May 18, 2006, 21:07 Re: About create new material #4 jasonchang Guest   Posts: n/a Dear chayriss ,opaque: I modify the setting just as what you suggest,it works well.Thank you. By the way,how to use ansys cfx10.0 to simulate solidification and fluid flow?I would appreciate if anyone can give me some advice. It was said that just CEL can set up the modelling,Is it true?I am not good at FORTRAN language. Thanks in advance.
