hi
I m trying to simulate Flow through porous media and I'd enter the permeability parameter from a tensor.But I do not know how? (ansys CFX-pre/defalt domaine/porous domaine/porosity setting/permeability) (for Simulation of Vacuum Assisted Resin Transfer Molding process) +--------------------------------------------------------------------+ | | | CFX Command Language for Run | | | +--------------------------------------------------------------------+ LIBRARY: MATERIAL: Air at 25 C Material Description = Air at 25 C and 1 atm (dry) Material Group = Air Data, Constant Property Gases Option = Pure Substance Thermodynamic State = Gas PROPERTIES: Option = General Material EQUATION OF STATE: Density = 1.185 [kg m^-3] Molar Mass = 28.96 [kg kmol^-1] Option = Value END SPECIFIC HEAT CAPACITY: Option = Value Specific Heat Capacity = 1.0044E+03 [J kg^-1 K^-1] Specific Heat Type = Constant Pressure END REFERENCE STATE: Option = Specified Point Reference Pressure = 1 [atm] Reference Specific Enthalpy = 0.

ANSYS CFX presently allows only K(permeability) to be isotropic ( Ansys CFX help)
