Component Contact
Use the Component Contact PropertyManager
to select components and set the default contact condition for all areas
that the selected components share amongst themselves or with other components.
You can apply multiple
contact conditions to override the global
contact setting by adding component contact and local contact sets.
Modifying or adding a contact condition requires remeshing the model.

for guidelines on studies with contact conditions.
Contact Type
The available options depend on the study type:
Selected components or bodies
do not penetrate each other during simulation, regardless of their initial
contact condition. By default, bodies do not penetrate themselves if the
deformation during simulation is sufficient to cause self-intersection.
Surface to surface contact formulation is applied for No
Penetration contact.
The No
Penetration component contact option is not available for nonlinear
studies. Use contact set definitions to apply No
Penetration contact between selected bodies.
Selected components or bodies behave as if
they were welded during simulation.
Selected components or bodies
can penetrate each other during simulation. Do not use this option unless
you are sure that loads will not cause interference of the components.
The Allow Penetration option overrides
existing component contacts. To apply Allow
Penetration contact to components or a top-level assembly, you
need to previously define a contact type.
See Types
of Contact. for more information on the above options.
Components
Global Contact. Selects the
top level assembly to apply a global contact condition.
Components for Contact 
. Select the components for which you want to specify contact
conditions with other components in the assembly. You can select the desired
components from the flyout FeatureManager design tree or from the graphics
area using the Filter Solid Bodies
tool 
on the Selection
Filter toolbar.
Options
(Visible for Bonded contact
only).
Compatible Mesh.
The program creates compatible mesh on initially contacting areas. If
the mesh is compatible, the program merges coincident nodes along the
common interface.
Incompatible
Mesh. The program meshes each component independently. If meshing
fails with the compatible mesh option, this option can help the meshing
process to succeed. In general, the compatible mesh option produces more
accurate results in the bonded regions.
Friction
(Visible for No Penetration
contact for static and nonlinear studies).
Friction Coefficient. Specify
a friction coefficient equal to or smaller than 0.5.
To set contact for components:
In the Simulation study tree, right-click the
Connections 
icon
and select Component Contact 
.
In the PropertyManager, select the desired contact
type.
In the Components
for contact 
, select the desired components from the
flyout FeatureManager design tree.
For Bonded
contact, select Compatible mesh
or Incompatible mesh. For No Penetration contact, specify Friction coefficient
.
Click 
.
An error icon 
appears next to the Mesh
icon when you modify or add any contact set. When you run the study, the
software re-meshes the model automatically before running the study.
