Modifying Automatic Solid Interface

Automatic solid interface finds contact between all fluids, solid parts, and regions in your model. When you enable thermal effects, it enables global conjugate heat transfer; when rigid body motions are active, it enables fluid-structure interaction.

When solid physics is present in your simulation, a solid interface feature is created automatically. This feature can be accessed through the dialog box or Scenario node in the tree. This feature can be edited or deleted.

Support Selection
  1. From the Contact section of the action bar, click Thermal Contact .
  2. Optional: Enter a descriptive Name.
  3. Optional: From the Support type options, select one of the following:
    OptionDescription
    Auto Detect the contact automatically between all parts and regions in the model.
    Surface Detect the contact only between the specified pair of surfaces.
    Region Detect the contact only between the specified pair of regions.
  4. From the Contact search parameters, specify the distance-based tolerance for contact by selecting one of the following choices from the Tolerance Type options:
    OptionDescription
    Absolute Specify tolerance as an absolute distance, then enter the distance in the Normal Tolerance field.
    Relative Specify tolerance relative to the typical mesh element size, then enter the relative size as a decimal in the Normal Tolerance field.
  5. From the Contact search parameters, specify the default Angle Tolerance for contact.
  6. Optional: When thermal effects are enabled, specify the Thermal Resistance that exists at the interface between the surfaces or regions.
  7. Click OK.
