Specifying heat generation for thermal contact property options

You can specify heat generation due to the dissipation of energy created by the mechanical or electrical interaction of contacting surfaces. For more information, see Modeling Heat Generated by Nonthermal Surface Interactions.

  1. From the main menu bar, select InteractionPropertyCreate.
  2. In the Create Interaction Property dialog box that appears, do the following:

  3. Click Continue to close the Create Interaction Property dialog box.
  4. From the menu bar in the contact property editor, select ThermalHeat Generation.
  5. In the editor that appears, specify the Fraction of dissipated energy caused by friction or electric currents that is converted to heat:

    • Choose Use default (1.0) to convert all of the dissipated energy to heat.

    • Choose Specify to enter the fraction of your choice.

  6. Specify the Fraction of converted heat distributed to secondary surface:

    • Choose Use default (0.5) to distribute the heat equally between the main and secondary surfaces.

    • Choose Specify to enter the fraction of the heat to be distributed to the secondary surface. The remaining fraction will be distributed to the main surface.

  7. Click OK to create the contact property and to exit the Edit Contact Property dialog box. Alternatively, you can select another contact property option to define from the menus in the Edit Contact Property dialog box.
