2D Indoor Wind Flow Visualisation Tool

Visualise airflow. Instantly.

BEM Studio is a browser-based 2D wind flow tool for architects and designers. Sketch a floor plan, set wind direction, and get an instant visual read on airflow patterns — right in your early-stage design process.

Capabilities

What the tool does — and what it doesn't.

🌬️
2D Pressure-Flow Solver
A simplified Gauss-Seidel pressure solver computes velocity fields each frame. It's not a full Navier-Stokes simulation — it's a fast, visual approximation suited to early-stage design decisions.
Core Engine
🧱
Interactive Layout Builder
Draw walls, openings, and vegetation directly on the canvas. Set the grid scale to match your space — from a single room to a building footprint. Results update immediately as you draw.
Layout Tools
📐
Zone Comfort Indicators
Colour-coded pressure and velocity overlays highlight stagnant areas, high-flow corridors, and sheltered zones. Useful as a qualitative guide — not a substitute for validated CFD or engineering assessment.
Indicative Only
🧭
Wind Direction & Speed
Set wind direction across 360° and adjust speed to explore how different conditions affect flow through your layout. Good for comparing natural ventilation options side by side.
Environmental
🎨
Flow & Pressure Overlays
Toggle particle streamlines, pressure heatmaps, and velocity vectors. The pressure field shows relative high and low zones — the values are indicative, not calibrated to real-world Pa readings.

Save & Share Projects
Save your floor plan and settings as a JSON file to pick up where you left off, or share with a colleague. Export canvas snapshots as PNG for use in reports and presentations.

03 — Build
Sketch your layout
Draw walls and openings on the grid, place vegetation, and set your wind conditions. The simulation runs continuously — no need to press a button to see results.
04 — Analyse
Read the flow patterns
Use pressure heatmaps and particle traces to identify dead zones, high-velocity corridors, and shelter effects. Treat the output as a qualitative starting point, not a final engineering answer.
