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:
MBD model files are files written using the Model Definition Language (MDL). These model files (*.mdl) can then be opened and saved in MotionView using the File menu, or the Open Model or Save Model buttons on the Standard toolbar.
The import feature facilitates reading in systems from the wizard library, or the MDL data statements (properties), or
a combination of the two using an MDL file. The export feature facilitates exporting wizard selection choices in the existing
model and/or the MDL data statements (properties), or a combination of the two into an MDL file.
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.
This feature is used to read in an MBD solver deck file.
Only the ADAMS Solver Deck is currently supported (see the
Loading an ADAMS*.adm File topic for additional information). The current model in
the data base will be erased and a new model will be created when this option is
selected.
From the File menu select Import > Solver Deck.
Or
Click the Import Solver Deck button on the Standard
toolbar.
Note: If the Import Solver Deck button is not visible on the
toolbar, click on the Import drop-down menu (the
arrow next to the current icon) and select the Import Solver
Deck option.
From the Import Solver Deck dialog, locate and select a relevant ADAMS.adm file to import using the Select
file browser.
Under Import Options:
Select Load standard include to automatically include
the definitions contained in the std_inc file in the MDL
model that resides in memory.
