CONTAM + Ventus

Model a safer world

Ventus is designed to provide a pressurization simulation for smoke control analysis. The simulation is performed by CONTAM, an open-source application maintained and developed by NIST.

Like PyroSim and FDS, Ventus provides a premium user experience for industry leading simulation software. By utilizing our expertise in delivering 3D modeling applications for fire protection eningeering, Ventus will exceed the demands of CONTAM users who want to accelerate their smoke control projects.

  1. Ventus allows users to build 3D models of pressure zones based on actual building geometry.
  2. Ventus manages multi-variable scenarios for simplified batch CONTAM simulation and analysis.
  3. Ventus tabulates results data for multiple scenarios into digestible CSV data and 3D visuals.

Whether for stairwells, atriums, or underground buildings, proper air handling systems must be designed for pressurized smoke control in case of emergency. Ventus provides a clear and efficient path from modeling a building to understanding temperatures, pressures, and densities so that the proper solution can be reached.

Thunderhead Engineering supports you every step of the way. Whether you want in-depth training or self-taught materials, you can learn performance-based design modeling with greater efficiency and proficiency. We design our software for anyone to learn, and our customers are delighted when our support team helps them succeed.
