Thunderhead

Ventus includes built-in error and warning checks. Issues are identified directly in the model, helping you locate and resolve problems during setup. Learn more: thunderheadeng.com/docs/2026-1/ve… #ventus #fireengineering #simulation

Advanced Pathfinder features continue to evolve. Assisted Evacuation is supported by updated documentation to help you build and refine your models. thunderheadeng.com/docs/2026-1/pa… #pathfinder #egressmodeling #firesafety

Mesh Refinement Zones increase resolution in targeted areas of your model. This allows for more detailed results where needed, without increasing overall cell count. #mesh-refinement-zones" target="_blank" rel="nofollow noopener">thunderheadeng.com/docs/2026-1/py… #pyrosim #firesimulation #bimworkflow

Select and filter flow paths in Ventus. Group by connections like shafts or stairwells, or filter by values to focus on relevant data. Learn more: thunderheadeng.com/docs/2026-1/ve… #ventus #fireengineering #simulation

Pathfinding verified with IMO 10. Green shows current seek curves. Red shows future paths and waypoints. Learn more: thunderheadeng.com/docs/2026-1/pa… #pathfinder #engineering

Ventus keeps a full history of your edits, so you can quickly undo, redo, and refine your workflow. Helpful for collaboration and iteration, especially when testing changes in complex models. #ventus #hvacdesign #engineering

Most fire models require multiple scenarios. PyroSim lets you manage them in a single file by enabling or disabling objects as needed. Less duplication. Easier updates. More efficient simulations. thunderheadeng.com/docs/2026-1/py… #pyrosim #firesimulation #engineeringworkflow #bim

Use queues to move occupants through unassigned seating or event layouts. This makes it easier to model realistic movement patterns over time, especially in large or dynamic spaces. #pathfinder #crowdsimulation #engineering

Use Filter View to isolate parts of your model and troubleshoot more efficiently. thunderheadeng.com/docs/2026-1/py… #pyrosim #firesimulation #bimworkflow

The updated ordering page makes it easier to view pricing and generate quotes. store2.thunderheadeng.com/cart #pyrosim #pathfinder #ventus

Create occupant targets from CSV-generated occupants to model assigned seating faster. Ideal for large populations and reducing manual setup. Learn more: thunderheadeng.com/docs/2026-1/pa… #pathfinder #crowdmodeling #firesafety #bim

Object tags help you organize and find related elements across your model. You can group unrelated objects, select them quickly, and manage edits more efficiently. #pyrosim #firesimulation #bim #engineeringworkflow

Use Level Working Z to adjust floor position and control level clipping. This makes it easier to work with vertical geometry and review elevation changes in context. #ventus #hvac #engineeringtools

Triggers add behavior based on location. They help model how occupants respond to their environment. Learn more: thunderheadeng.com/docs/2026-1/pa… #pathfinder #crowdsimulation #engineering

Auto Expand Selection reveals selected objects in the navigation panel. This helps locate elements quickly in large models. #pyrosim #bimworkflow

As room designs change, flow paths need to be updated. Ventus lets you quickly redraw flow paths manually, so airflow and smoke modeling stays accurate. Learn more: thunderheadeng.com/docs/2026-1/ve… #ventus #hvacdesign #engineering

Dynamic obstacles support flexible pedestrian scenarios. They allow you to test how movement changes as layouts evolve. Learn more: #_editing_scenarios" target="_blank" rel="nofollow noopener">thunderheadeng.com/docs/2026-1/pa… #pathfinder #simulation #crowdflow

Use the level filter to isolate floors directly in 3D. This helps you review zones in context across multi-level models. #ventus #hvac #airflow #smokecontrol #engineering

Bulk renaming helps manage large models in PyroSim. Use Rename with Template to convert complex CAD mesh names into clear, consistent labels for easier navigation and communication. Learn more: thunderheadeng.com/docs/2026-1/py… #pyrosim #firesimulation #engineering #fds

Queues help coordinate pedestrian movement through a space. They provide a structured way to define flow and test how layouts perform under real conditions. Learn more: thunderheadeng.com/docs/2026-1/pa… #pathfinder #crowdsimulation #engineering #pedestrianmodeling
