PyroSim and FDS

FDS/PyroSim Workshop

This 2-day workshop is an introduction to FDS and PyroSim. It gives the big picture and is suitable for managers, AHJs (who don’t want to learn how make their own models) and beginning modellers.

  • 2-day Workshop
  • Designed for beginning modellers and AHJs
  • Laptop required
  • Workshop fee $1,000 USD

Day 1:

  • Introduction to FDS and Smokeview
  • Hardware and Software Requirements
  • Elements of building a model
  • Hands-on Construction of a Simple model using PyroSim (The simulation will run overnight on the participant’s laptop.)

Day 2:

  • Using Smokeview to View the Results of a Simple model
  • Data Collection
  • Reactions
  • Fires
  • Materials
  • Surfaces
  • Sprinklers and Suppression
  • Performance-based Design, with Examples
