VISRAD Overview


VISRAD is a 3-D thermal radiation and CAD code that simulates the reflection, emission, and absorption of light radiation throughout a complex system of surfaces. This view factor code features a user-friendly graphical interface for setting up 3-D object grids and displaying results from directed laser light and thermal radiation calculations.

VISRAD includes customized features that allow for easy setup and simulation of High Energy Density Physics (HEDP) experiments at major research laboratories.

With VISRAD, someone can easily set up a grid of surfaces, and simulate radiation flux and temperature distributions throughout the grid. It also includes pre-configured laser-beam and diagnostic port systems that allow for convenient setup, viewing, and simulation of laser beam experiments.

Supported Laser Beam and Diagnostic Port Systems

VISRAD currently includes pre-configured systems for the following laser facilities:

  • OMEGA 60-beam system at University of Rochester's Laboratory for Laser Energetics
  • OMEGA EP (Extended Performance), an addition to OMEGA that provides pulses of multikilojoule energies, picosecond pulse widths, petawatt powers, and ultrahigh intensities
  • NIF (National Ignition Facility) 192-beam system at Lawrence Livermore National Laboratory
  • LMJ (Laser MegaJoule) at CEA, France
  • For NIF laser beams, in addition to the primary (3ω) beams, VISRAD also computes laser power deposition from unconverted laser light (1ω and 2ω).
