About Thunderhead Engineering

Thunderhead Engineering develops a suite of simulation software for science and engineering, including PyroSim for fire/smoke, Pathfinder for pedestrian movement, and Ventus for airflow analysis.

Thunderhead Engineering provides a suite of specialized simulation software for engineering and scientific applications, primarily focused on safety and building performance. The main products are PyroSim (a graphical interface for FDS fire and smoke simulation), Pathfinder (for pedestrian and crowd egress modeling), and Ventus (an interface for CONTAM airflow and smoke control simulation). These are desktop applications for Windows, targeted at fire protection engineers, safety consultants, and building designers. The software supports importing CAD/BIM files. Pricing is not publicly listed, requiring a quote, but a 30-day free trial is available. Support is offered via a help portal, email, and extensive documentation.

Pros & Cons

Pros
  • Provides a specialized suite of advanced simulation tools for fire, smoke, and pedestrian dynamics.
  • Acts as a user-friendly graphical interface for powerful, industry-standard simulation engines like FDS and CONTAM.
  • Offers a 30-day fully-featured free trial for its products.
  • Extensive documentation is available for all software versions.
  • Supports import of CAD and BIM files, streamlining model setup.
Cons
  • Pricing is not publicly available and requires requesting a quote.
  • The software is a suite of separate desktop applications, not a single integrated cloud platform.
  • Primarily runs on Windows, with no native support for Mac or Linux.

Features

Key features

PyroSim Fire & Smoke Simulation

A graphical interface for the Fire Dynamics Simulator (FDS) to analyze fire control and smoke dissipation in various structures.

Pathfinder Pedestrian Simulation

Models crowd movement, ingress, egress, and queuing for life safety analysis and event planning.

Ventus Pressurization and Smoke Control

A graphical interface for the CONTAM engine to simulate airflow, pressurization, and contaminant transport in buildings.

CAD and BIM Import

Imports geometry from CAD and BIM files to accelerate model creation.

Advanced Results Visualization

Creates detailed plots and videos with advanced controls and information overlays to communicate simulation results.

Additional features

Simulation Management

Control CPU processing and maintain multiple simulation configurations for sensitivity analyses.

HVAC and Duct System Design

Ventus includes tools for designing 3D duct systems.

Emergency Response Modeling

Pathfinder can model reactions to emergencies, including assisted evacuation and exposure to fire conditions.

Code Compliance Analysis

The software suite is designed to help engineers comply with safety codes and standards from bodies like ASHRAE, NFPA, and IBC.

Scripting Toolkit

Pathfinder includes a Python-based scripting toolkit for creating custom tests and suitability data.
