SIM introduction

Learn how SIM organizes vehicle setup, inputs, simulations, and analysis for 4ACE workflows.

SIM is the 4ACE product area for preparing simulation inputs, running simulations, and analyzing results in a team workspace.

Use this section when you need to build a vehicle model, prepare reusable setup data, run FastSim or OpenSim, and review output with your team.

SIM workflow

Create reusable aerodynamics, body, brakes, drivetrain, steering, suspension, tires, lookup tables, and polynomials.

Select setup modules into one vehicle assembly for simulation work.

Choose FastSim, OpenSim, or Batch Simulations and submit runs.

Choose Detailed Analysis, Batch Analysis, and reusable analysis layouts for telemetry review.

Input	Where it lives	Use it for
Vehicle	Vehicles	Select one assembly of body, suspension, steering, brakes, drivetrain, aerodynamics, and tires.
Submodules	Design	Maintain reusable setup blocks that vehicles reference.
Lookup tables	Vehicles > Lookup tables	Define 1D and 2D numeric maps used by selected submodule parameters.
Polynomials	Vehicles > Polynomials	Define coefficient-based curves for parameters that support polynomial mode.
Driver	Drivers	Select the driver profile for simulation context.
Circuit	Circuits	Select the track file and map data for circuit-based work.
Ambient	Ambients	Select environmental and track condition inputs.
