the Best Practices for Specifying Contact Conditions
This section describes some of the practices you should try to keep in mind while defining the properties of the contact conditions for your model.
Mesh Requisites
Selecting Contact Formulation
Overlapping Contact Conditions and Boundary Conditions
Contact Behavior
Initial Contact Tool
Diagnostic Tools, NR Residuals, and Contact Result Trackers
Contact Tool Results
Mesh Requirements
Defining a proper mesh is critical to contact conditions. A well-defined mesh ensures accurate stress measurements at a contact region. Furthermore, a quality mesh is essential for nonlinear contact conditions in order to obtain an accurate solution. This is especially true for curved surfaces. Use local Mesh Controls, such as Proximity Controls and Contact Sizing controls to better ensure mesh quality. Review the Apply Mesh Controls and Preview Mesh section of the Help for more information on this topic.
Selecting Contact Formulation
Mechanical provides the following options for the Formulation property:
Augmented Lagrange
Pure Penalty
MPC (Multi-Point Constraint)
Normal Lagrange
