Course Catalogue.

After participating in this course, you will be able to:

• Build and run fire dynamics simulations using PyroSim to evaluate fire and smoke behaviour in enclosed spaces
• Assess toxic gas production and concentration results to support life safety and risk decisions
• Analyze heat transfer and material thermal response under steady state and transient fire conditions
• Apply best practices for meshing, boundary conditions, and model setup to produce defensible results
• Interpret FDS outputs to validate assumptions and inform fire safety and performance assessments

Description

Fire and smoke modelling is increasingly relied upon to support safety-critical decisions in building design, code compliance, and performance-based fire engineering. Yet creating a simulation that is both technically sound and defensible requires more than knowing which inputs to assign—it requires understanding how modelling choices affect results, interpretation, and risk.

This one-day, hands-on workshop is designed to strengthen your ability to use PyroSim (FDS) as a practical analysis tool. Through guided simulation exercises, you will work with realistic fire scenarios involving toxic gas production, heat transfer through building assemblies, and pool fire behaviour. Each exercise emphasizes not just how to run a model, but how to evaluate outputs, validate results, and recognize limitations.

By completing this course, you will gain practical, structured experience that you can apply directly to fire safety evaluations, material performance analysis, and performance-based design decisions in your professional practice.
