7. External Model

The following External Model system enhancements were made at Release 2026 R1:

  • External Model Browser. For the Windows operating system, the new External Model Browser window enables you to view the processed and unprocessed keywords/commands for supported file types imported into the Mechanical application using External Model options. The browser displays a tree of supported keywords/commands and options that enable you to preview properties or to add a keyword or command to the analysis through a command object.

  • Imported MPC and Joint Connections. You can now import mesh-based Multi-Point Constraints (MPCs) from Mechanical APDL common database (*.cdb) files using the External Model system.

  • Imported Shell Thicknesses. You can now import variable shell thickness data for ABAQUS, NASTRAN, LSDYNA, and Mechanical APDL common database files. The application supports variable thickness on each corner node. Once imported, the Worksheet for the Shell Thicknesses object provides options that display the thickness values for each node.

  • New Pyramid Element Type Support. You can now import the following pyramid elements:

    • ABAQUS: C3D5 (linear) and C3D13 (quadratic)

    • NASTRAN: CPYRAM (with the option of being linear)
