Defining thermal conductance for gasket/cohesive elements

You can use the Edit Material dialog box to define thermal interaction between the top and bottom surfaces of a coupled temperature-displacement gasket element and coupled temperature-displacement cohesive elements.

For more information, see:

  1. From the menu in the Edit Material dialog box, select Thermal Gap Conductance.

    (For information on displaying the Edit Material dialog box, see Creating or editing a material.)

  2. Toggle on Use pressure-dependent data to define the gap conductance parameters as a function of pressure.
  3. Click the arrows to the right of the Number of field variables field to increase or decrease the number of field variables on which the gap conductance depends.
  4. Enter the following data in the Data table:

    Gap Conductance

    Gap conductance or cohesive separation, k.

    Gap Clearance, Gap Pressure, or Closure

    Gap clearance, gap pressure (if Use pressure-dependent data is toggled on), or closure (for coupled temperature-displacement gasket elements).

    Field n

    Predefined field variables.

    For detailed information on how to enter data, see Entering tabular data.

  5. Toggle on User Defined to define the gap conductance in user subroutine GAPCON. Other parameter settings and any data lines are ignored.
  6. Click OK to close the Edit Material dialog box. Alternatively, you can select another material behavior to define from the menus in the Edit Material dialog box (see Browsing and modifying material behaviors, for more information).
