ASAP Workflow

SPOTLIGHT // VECTRIX ELECTRIC SCOOTER: BRO Engineering Services used ASAP to design the headlight, stoplight, and turn signal illumination systems for the Vectrix all-electric scooter. ASAP accurately modeled the slope errors that result from reflector manufacturing processes, as well as scatter from roughness and imperfections in metallic coatings applied to the reflectors. The Vectrix scooter is now in production and available for purchase.

 

Step 1: System Setup

Every optical system simulation begins with an accurate geometrical model. Import your system geometry from a CAD program in formats such as IGES, STEP, or XML, or use the proprietary BRO GTX file format to import from SolidWorks® 3D CAD software, which customers have the option to bundle with ASAP. During import, ASAP users may remove duplicate and unnecessary surfaces, as well as condition geometry for ray tracing. CATIA® users also have the option to open native CATIA files in ASAP. The powerful ASAP script language and spreadsheet-style Builder environments also provide many options for modeling system geometry ranging from simple fixed-dimension surfaces to complex systems with dimensional parameterization, which allows geometrical entities to be treated as variables in system-optimization procedures.

Following geometrical system characterization, optical properties are defined to tell the analysis engine how to treat optical interactions such as transmission, absorption, diffraction, polarization, and scattering. ASAP handles them all. Comprehensive material libraries accelerate system setup but when measurements for new materials must be used, the BRO Digitizer provides maximum flexibility for entering optical properties data and the BSDF fit utility allows fitting complex scatter models including the all-important Harvey scatter model. During system definition, 2D and 3D visualization tools ensure that everything is in place before the next step in the ASAP workflow.

Step 2: Define Sources

Every system requires an accurate source model, and ASAP sources are the best in the industry. ASAP comes standard with hundreds of ready-to-use sources that save users hours.

Key Source Definition Features

  • Source wizard and LED, CCFL, incandescent, and arc sources
  • Use point sources, ray fans, grids and other ASAP sources
  • Calculate and visualize extended-source illumination patterns

Step 3: Run Simulation

Once your system geometry, properties, and sources are defined, you're ready to trace rays. With ASAP, you get the fastest non-sequential ray tracing engine available, as well as REMOTE™ for distributed processing — so you won't be waiting long for results.

Key Simulation Features

  • Perform polychromatic ray traces
  • Trace forwards, backwards, and stepwise in your system
  • Trace rays to regions of importance within your system
  • Verify polarization, scatter, and coherence at any surface
  • Track individual rays and visualize ray traces as they occur

Step 4: Perform Analysis

When your ray trace finishes you'll be ready to perform analysis, and the analysis features in ASAP are second to none. ASAP includes everything you need to evaluate your ideas, optimize your system, and visualize, interpret, and share results — taking into consideration the most complex of optical phenomena.
