Solver interfaces supported in HyperWorks.
A solver interface is made up of a template and a FE-input reader.
Browsers supply a great deal of view-related functionality by listing the parts of a model in a tabular and/or tree-based format, and providing controls inside the table that allow you to alter the display of model parts.
Create and edit 2D parametric sketch geometry.
Create, edit, and cleanup geometry.
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.
Different types of mesh you can create in HyperWorks.
Create and edit 0D, 1D, 2D, and 3D elements.
Create, organize and manage parts and subsystems.
HyperMesh composites modeling.
Create connections between parts of your model.
Rapidly change the shape of the FE mesh without severely sacrificing the mesh quality.
Create a reduced ordered model to facilitate optimization at the concept phase.

MotionView supports the importing of several types of CAD and FE formats.
MotionView has many pre-processing and post-processing capabilities with regards to flexible bodies, or flexbodies, for multi-body dynamics models.
From the Preferences dialog, you can access various MotionView options for your model.
This section describes how to build events in the full vehicle model with Altair Driver. The new event user interface is supported only for models with Altair Driver. The interface exports .adf and .xml files and submits them to MotionSolve. Files can be edited or updated in the Event Editor. Eighteen event types are supported.
A Constant radius event simulates a vehicle driving in a circular path, typically with increasing speed. The event predicts the vehicles roll and understeer characteristics with increasing lateral acceleration.
A Single lane change event drives the vehicle through a single lane change, attempting to follow the centerline of the defined lane.
A Double lane change event drives the vehicle through a lane change and a return to lane maneuver, attempting to follow the centerline of the defined lane.
A Swept Sine event simulates a vehicle driving at a constant speed with a sinusoidal steering input of constant magnitude but increasing frequency applied.
A Straight line acceleration event simulates a vehicle accelerating at a constant rate in a straight line.
A Straight line Braking event simulates a vehicle slowing in a straight line.
A Sinusoidal steering event simulates a vehicle driving at a constant speed while a sin wave input is applied to the steering wheel.
A Braking in a turn event simulates a vehicle decelerating in a circular path.
A J-turn event simulates a vehicle response to a large steer in one direction, a dwell time to allow the vehicle to react, and a large steer in the opposite direction, with an additional reaction time.
A Throttle-off cornering event simulates the dynamics of a vehicle driving a constant radius turn at steady state and the reaction of the vehicle due to a sudden removal of the drive torque while cornering.
A Swept steer event simulates a ramped steer input into a vehicle driving at a steady speed.
A Pulse steer event simulates a vehicle response to a sudden pulse input to the steering wheel while driving in a straight line at a constant speed.
A Throttle-off turn-in event simulates a vehicle driving straight at constant speed, turning on to a constant radius, then after reaching steady state the throttle is closed and the steering is ramped to tighten the turn.
A Step steer event simulates vehicle response to a sudden step input to the steering wheel.
A Power-off in a straight line event simulates the dynamics of a vehicle due to a sudden removal of drive torque.
The Altair Driver File event allows you to run your own Altair Driver File and use this file in the event.
The n-Post Shaker event simulates a vehicle supported on a test-rig by posts.
The Stability Analysis event can be used to simulate two-wheeler models on various road surfaces to evaluate the weave and wobble modes of the vehicle. A user-defined road property file determines the road input.
A Slalom event drives the vehicle in a straight, followed by a sequence of turns around cones in alternate directions. The vehicle velocity is held constant.
The Altair Driver is a set of MotionView models and libraries that allows MotionView users to control and script vehicle events.
Controllers form the core of the driver. The Controller Library has various basic controllers its arsenal to calculate different driver outputs.
Driver can be loaded using the Model Wizard of MDLLIB when the Full Vehicle with Driver option is chosen. Driver has some special requirements to interface with the vehicle model. These requirements are resolved automatically if the vehicle model is built using the Full vehicle with advanced driver option in the Model Wizard in MDLLIB.
Driver uses the Altair Driver File (ADF) to access all the event parameters in the Solver.
