Ventus 2026: baixar versions anteriors

This release of Ventus has some powerful new features that all users will appreciate. Download the new version to work faster in 3D with multi-height Zones and Section Boxes.
Zone Height Property Independence
For this release, we have made the Zone height properties independent of Level assignment, allowing users to create multi-height Zones on each Level and multi-Level Zones. This change provides greater flexibility in modeling complex building geometries and allows for more accurate representation of real-world scenarios where different parts of a Level may have varying heights.

This change matters because it expands the flexibility of using Ventus to model vertical airflow. For example, use a multi-hieght Zone to model an atrium in the updated example:

There are also updates to the 3D tools for drawing Flow Paths to accommodate multi-height Zones, ensuring that users can easily create and visualize models with more complex geometries. For example, when Level visibility changes, objects are now shown/hidden as whole objects. Read the 2026.2 Changelog for more details.
Section Boxes
We added support for Section Boxes for the 3D Workspace. The feature provides a flexible tool to limit the visibility of geometry to a user-defined region.

CAD Quality Adjustment
For years, Ventus has supported importing CAD geometry. However, users do not always have access to concise models with relevant geometry. Often, there are many CAD objects that complicate and slow down Ventus.
Enjoy new options to optimize performance with imported geometry and keep certain CAD details higher-quality.
- On import, you can specify Object Quality (See the Creating Geometry from CAD page). This reduces the number of triangles used to represent imported geometry.
- After import, you can perform a similar operation upon any selected imported geometry. The new context-menu action allows users to Simplify Imported Geometry.

HVAC Results Support
Ventus 2026.2 continues support for modeling complex HVAC duct systems. Duct Junction and Duct Segment results can now be inspected in the Results panel.

Documentation Improvements
The 2026.2 release includes extensive revisions to product documentation, focused on adjusting existing content to reflect the new multi-height Zone capabilities and the full suite of tools. More details can be found in the 2026.2 Changelog, including a roadmap for new users to learn Ventus 2026.2.

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.

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 improvements aimed at making the software more reliable and intuitive. The user interface has been clarified to reduce confusion and streamline workflows, while underlying CONTAM updates enhance simulation accuracy and compatibility. Numerous bug fixes have resolved known issues, and major OpenGL updates improve rendering stability, providing smoother and more consistent visualization of models and results.
Documentation Improvements
The 2026.1 release includes a major overhaul of the product documentation, focused on making information easier and faster to access. Navigation has been significantly improved through the introduction of pagination, allowing users to move more quickly between sections, while a new document-wide search tool makes it easier to find specific topics and answers. Pages that are new or have been updated are now clearly highlighted, helping users quickly identify what has changed in the latest release.
In addition, previously separate manuals and content have been consolidated into a single, unified document, reducing fragmentation and simplifying the learning experience. The documentation has also been reorganized to improve the discoverability of related content, making it easier for both new and experienced users to explore features, understand workflows, and find relevant guidance without unnecessary searching.
Explore the updated documentation by trying the new search tool located at the top of the documentation table of contents, which provides a quick way to jump directly to relevant information. Be sure to review the Examples section (formerly Tutorials) for practical, step-by-step guidance, visit Troubleshooting (previously FAQs) for help resolving common issues, and explore the Advanced Topics and Appendices for deeper technical detail and reference material that support more complex use cases.
