Thunderhead Engineering provides training on the use of our software as described in the sections below. Pathfinder training is typically scheduled in conjunction with PyroSim workshops.

Who Should Attend

  • AHJs
  • Fire Investigators
  • Fire Engineers
  • Fire Safety System designers
  • Smoke Management System designers
  • Risk Management Consultants
  • Insurance Assessors and Loss Adjusters
  • Building Surveyors

Workshop Benefits

  • Small class size gives you more one‐on‐one time with the instructor
  • Hands‐on application lets you learn from experience
  • Current, relevant information keeps you up‐to‐date with industry knowledge
  • Participants can pursue their FDS learning after the workshop through a supervised project with the instructor
  • A 90‐day license for the software is provided

Online Workshops Now Available

Online workshops will be conducted on Zoom. Each participant will require a second screen so they can watch the instructor’s demonstration on one screen and follow along on their own screen. A microphone is required for asking questions, and a camera is a nice feature, although not mandatory.

The content is the same as the 2-day workshops described below.

PyroSim and FDS
