From the Connections section of the action bar, click Contact Detection.
Specify a Search domain.
By default, the app searches the whole model for contacting surfaces. You can select candidate
geometry supports by clicking individual components in the model. The app considers contact features between the selected components only. If you
select a single component, the app only considers the contact features between surfaces on the selected
component and any other contacting surfaces in the model.
For linear structural simulations, select one of the following
Structural interaction options:
Option
Description
Sliding
Allows two surfaces to move sideways with respect to each
other.
Bonded
Conjoins two surfaces permanently without the ability to move with
respect to each other.
Note:
In a nonlinear structural simulation, buckling simulation, or frequency
simulation, you cannot create surface-based sliding contact; the only choice
is Bonded. In a nonlinear structural simulation,
however, you can use general contact to configure sliding contact throughout
the model.
Click Find Surface Pairs.
The dialog box lists candidate contact features for surfaces that meet
the proximity requirements. Right-click any feature to locate or delete
it.
Optional:
To change the search domain, click Find Surface Pairs
again.
Any new surface pairs found are marked by an asterisk (*) in the
table.
For thermal simulations, enter a value for the
Conductance, which is a measure of the conductive
heat transfer between the contacting surfaces.
A higher conductance value implies an easier transfer of heat across the
surfaces, while a conductance of zero prevents heat from transferring across the
surfaces.
For thermal-structural simulations, define both the thermal and mechanical
interaction between the surfaces.
For the Structural interaction, select
Bonded or None.
For the Thermal conductance, enter a value for
the thermal conductance between the surfaces.
A higher conductance implies an easier transfer of heat between
components, while a conductance of zero prevents heat from transferring
across the surfaces.
If you do not enter a value, the default behavior
is fully conductive.
