6.13.1.3.4. Imported Constraint Equations or Coupling

When your upstream External Model source file includes constraint equations or coupling, an Imported folder appears beneath the Connections parent folder when you open the file in Mechanical. This object is a simple group folder. It contains the child object: Constraint Equations. The data associated with the imported equations is provided through the Worksheet. You can deactivate/active Worksheet entries using the Active selection box in the table or through the right-click context menu.

Supported Analysis Types

Constraint Equations and Coupling import types are supported by the following analysis types:

  • Coupled Field Analyses

  • Harmonic Response

  • Modal

  • Static Structural

  • Transient Structural

  • Steady-State Thermal (Coupling only)

  • Transient Thermal (Coupling only)

Supported Source File Commands

The application imports the following source file data/commands as constraint equations or coupling:

  • CDB: The CE commands are processed as constraint equations and the CP commands are processed as couplings.

  • NASTRAN: MPC commands are processed as constraint equations.

  • ABAQUS: *EQUATION commands are processed as constraint equations and *MPC TIE commands as couplings.

See the Imported: Constraint Equation object reference section for additional information.
