Independent mode relies on the independent Mechanica user interface for all simulation modeling, analysis and design study execution, and results viewing. In independent mode, you have the option of building your model geometry in Pro/ENGINEER, importing geometry from a third-party CAD package, or building the geometry exclusively within Mechanica. After you work with your model in independent mode, you break all association with Pro/ENGINEER and you can no longer automatically update the Pro/ENGINEER model from Mechanica.

Here are some features of independent mode:

You can create elements manually or automatically. For solid models, you can create solid elements such as tetrahedrons, wedges, or bricks. For shell models, you can apply triangular and quadrilateral shell or plate elements. As an option, you can manually add several specialized element types to your model. These element types include beams, spot welds, springs, and masses.

Mechanica provides a variety of manual element generation methods including geometry selection, point seeding, extrusion, and revolution. If you want Mechanica to create elements automatically, you can use AutoGEM, a tool that generates elements on curves, surfaces, and volumes.

You indicate which aspects of your model can change during a sensitivity or optimization study by defining design variables for dimensions and design parameters for properties. You cannot, however, use Pro/ENGINEER relations or parameters to control shape changes.

You can create element-based measures to get information on stress intensity factors (cracking) in your model, resultant forces and moments, and net heat flux.
