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.

Forces
The *SetForce() command set statement writes a force statement to
the solver command file. This statement sets the value of the force to the specified
value when the solver acts on that line in the command file.
Simulate
Exports the simulation commands to the solver command file.
Motion
The *SetMotion() command set statement writes a motion statement
to the solver command file. This statement sets the value of the motion to the
specified value when the solver acts on that line in the command file.
SetState
One command set can be active in any one analysis task. MDL saves the state of each
command set in the *SetState() statement.
