Driver File

You can begin with an existing event and modify it or write your own event file. Additional information on writing the events can be found in Full Vehicle Events and Altair Driver.

This Driver File event is supported by the Cars & Small Trucks, Heavy Trucks, and Two-Wheeler vehicle libraries.

Parameters


Parameter Name	Description
Altair Drive File	ADF file input with event settings

Road Settings

Three options are available to specify the road in the event, Flat Event, Road File, and Tires.

Flat Event

Uses a flat smooth road for the event with no required road file.

When the Flat Event is selected, the Graphics Setting option is available with the following parameters:

View path centerline: Enables the visualization of the event path.
- This check box is disabled for open loop events without a path.

View grid graphics: Enables the visualization of the road grid graphics.

When view grid graphics check box is toggled, road grid parameters can be edited in the Grid Settings tab.


Grid length	Defines the length of the road. Enter a positive value in the model units.
Grid Width	Defines the width of the road. Enter a positive value in the model units.
Grid X offset	Gives a distance offset to the road graphics in the longitudinal direction. Enter a positive value in the model units.
Grid Y offset	Gives a distance offset to the road graphics in the lateral direction. Enter a positive value in the model units.

Road File: The road file option enables the selection of a road file to be used in the event. The road property file used in this option overrides the road property files used in the Tire entities within the model. The road property file should be compatible with the tire property file that is used in the vehicle.
Tires: Using Tire as road selection option, the road file specified in the tire entity is used in the events simulation.

Simulation Settings

Analysis Parameters

Define the numerical and output settings for the simulation:


Parameter Name	Description
Print interval	The time step between successive outputs of simulation results.
Real-Time Empowered	When enabled, MotionSolve builds the FMU of the vehicle and solves it in real-time.
Code generation	When enabled, the C code for the MotionSolve Vehicle model excluding the driver and tire will be generated. This code can be used to compile and build an FMU, which can be used with any FMU compatible software.

For more information see the Parameters: Simulation - Attributes topic.

Dynamic Settings: Defines the simulation control parameters for a time-domain-based nonlinear dynamic analysis. For more information see the Parameters: Transient Solver - Attributes topic.
Static Settings: Defines the solution control parameters for static and quasi-static analysis. For more information see the Parameters: Static Solver - Attributes topic.
