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

• Understand the practical workflow of FDS modeling in PyroSim.
• Model fire and smoke behavior in enclosed spaces under varying fuel and structural conditions.
• Analyze toxic gas concentrations and their life safety implications.
• Simulate material thermal response under steady-state and transient fire conditions.
• Learn best practices in meshing, boundary conditions, and interpreting simulation data.

Description

This one-day intensive workshop provides participants with applied training in fire dynamics simulations using PyroSim (FDS). The course emphasizes hands-on learning through three structured practice problems based on real-world scenarios, enhancing understanding of combustion dynamics, toxic emissions, heat transfer, and structural response in fire environments. By the end of the workshop, participants will have developed modeling proficiency and analytical interpretation skills to assess fire safety and material performance in buildings.

Who Should Attend

• Overview of FDS and PyroSim software environment

Practice Problem 1 – Toxic Gas Analysis in Fire (Polymers)
Model the combustion of 0.5 kg of Polystyrene (PS) and 0.5 kg of Polyvinyl Chloride (PVC) in a closed room:

• Define combustion chemistry for PS and PVC
• Model toxic gases: CO and HCl using gas-phase devices
• Analyze gas concentrations and toxicity risk to occupants

Practice Problem 2 – Heat Transfer in Sauna Walls
Simulate steady-state heat conduction through wall and roof assemblies in a sauna built with wood framing:
