FE geometry is topology on top of mesh, meaning CAD and mesh exist as a single entity. The purpose of FE geometry
is to add vertices, edges, surfaces, and solids on FE models which have no CAD geometry.
A multibody system study generally involves the following broad steps. The following sections give a brief introduction
on using MotionView and the related HyperWorks products to conduct such a study:
MotionView supports and encourages a modular model building approach. Different entities can be aggregated into containers, thereby
arranging a model into a collection of different assemblies or sub-systems.
The expression builder allows you to enter expressions in text boxes without extensive typing and memorization. It
can be used to construct mathematical expressions that are a function of the model parameters.
MotionView contains an implicit variable called SolverMode. In MDL, SolverMode can be used in an "if" context to define topology (include Templex templates). MotionView retains the "if" result for both cases so that when you toggle the solver type, the associated text becomes active
within the user interface.
Batch mode allows you to generate a solver input model file from an MDL model file and run the solver job without starting
the MotionView user interface.
Check Model searches for unresolved references and invalid data in the model. If errors in the model are detected,
it is reported in the message window that is displayed when the check is completed.
The Command Sets panel allows you to create command sets for the solver-command file. The command sets for a model are
order dependent, since they define the contents of the solver command file.
Implicit graphics can be displayed for all applicable entities, allowing you to
visualize their location and orientation.
Visualization helps you control which implicit graphics
are active, as well as size entities and select whether the entity is sized relative to
the model or relative to the screen. You can also control the color of each entity.
Entities containing implicit graphics include:
Points
Bodies
NLFE Bodies
Markers
Joints
Advanced Joints
Couplers
Bushings
Spring Dampers
Beams
PolyBeams
Forces
Motions
Deformable Curves
Deformable Surfaces
Contacts
From the Model menu, click Implicit Graphics.
The Implicit Graphics Settings dialog is displayed.
Activate the check boxes in the Visible column for the implicit graphics that
you want to display.
Activate the check boxes in the Zoom column for the implicit graphics that you
want to change size in a zoom, .
Enter a value in the Size text box to change the size of a specific implicit
graphic.
Click on a color box for the implicit graphic that you want to change
color.
Click Close to close the Implicit Graphics Settings
dialog.
