winget install --id Thunderhead.Ventus.2026About Ventus 2026
Ventus is developed by a team of experienced engineers and software developers to address the specific needs of building safety engineers. Ventus helps you design air handling systems for the crucial work of managing airflow and preventing the spread of contaminants during emergency scenarios inside of your building spaces. By strategically managing airflow, the systems you design will be able to maintain tenable conditions in critical Escape Routes, including Stairwells, Shafts, Atria, and Underground Facilities....
What's new in 26.1.0211
HVAC Support Ventus 2026.1 introduces preliminary support for modeling more complex HVAC duct systems, expanding the product’s capabilities for detailed airflow analysis. Users can now create Duct Junctions, Duct Segments, and Duct Flow Elements to represent realistic duct layouts, while results at Duct Junctions can be visualized directly in the 3D workspace as vector data. This new functionality allows for more intuitive inspection of airflow direction and magnitude, helping engineers design, analyze, and optimize HVAC systems with greater confidence. Figure 1. An example model using ducts in Ventus. You can read more about Ducts in the Ducts section of the Ventus Documentation. Additional Flow Element Support Ventus also introduces support for several new flow element types, providing more precise options for modeling airflow and leakages. The Crack Description element allows users to simulate leakages using measured door crack dimensions, making it easier to represent real-world gaps and penetrations. Test Data (1-Point) and Test Data (2-Point) elements enable modeling of leakages based on empirical test data for well-studied building components, improving accuracy for validated scenarios. Additionally, the Darcy-Colebrook flow model has been added for duct flow elements, offering a more sophisticated method for simulating duct systems. You can read more about the new Flow Elements in the Powerlaw Models and Duct Flow Elements sections of the Ventus Documentation. User Experience Improvements The latest Ventus release includes several user experience and stability impro...
