I would like to specify orthotropic thermal conductivity in a solid domain using CFX.
Please note that this approach works only if all solid interfaces are 1-1. To use Orthotropic Thermal Conductivity you need to edit the CCL definition of a material, you cannot set this up using the GUI as of CFX-10. Change the following CCL in the required material: From: THERMAL CONDUCTIVITY : Option = Value Thermal Conductivity = ` [W m^-1 K^-1] END To: THERMAL CONDUCTIVITY : Option = Orthotropic Cartesian Components Thermal Conductivity X Component = `. [W m^-1 K^-1] Thermal Conductivity Y Component = ` [W m^-1 K^-1] Thermal Conductivity Z Component = `. [W m^-1 K^-1] END You can also use a cylindrical coordinate frame if necessary or create your own Cartesian/cylindrical frame if your geometry does not line up with the default axes. Please search the online help for Orthotropic to obtain additional details. |
