ElfireApp 🔥

Fire Compartment Analysis Tool based on Eurocode & International Standards

---

📌 Overview

ElfireApp is a Windows Forms-based engineering software designed to model fire growth and temperature development in enclosures. It allows users to calculate Eurocode-based parametric fire curves, as well as compare them with ISO 834, Hydrocarbon, and ASTM E119 standard time-temperature curves.

With its modular architecture and user-friendly graphical interface, ElfireApp enables professionals to simulate realistic fire scenarios based on geometric, material, and risk-related parameters.

🧮 Core Features

🔧 Compartment Designer

• Define geometry: length, width, height

• Calculate enclosure, wall, ceiling, and floor areas

• Add openings manually or calculate via opening factor

🧱 Material Properties

• Select or define new materials for walls, floor, and ceiling
• Automatically computes thermal inertia of the compartment

🔥 Design Fire Parameters

• Import fire load & ROFI data (Occupancy / Floor Area)
• Apply risk factors based on real occupancy types and area categories
• Customize combustion factor, fire duration, and suppression coefficient

📈 Curve Generation

• Calculate temperature-time data for:
  • Ventilation-Controlled Fires
  • Fuel-Controlled Fires
• Determine max temperature, duration, and other critical fire parameters

📊 Visualization

• Dynamic plotting of fire curves (with tooltips, phase filling, labels)
• Comparison module for:
  • ISO 834
  • Hydrocarbon Fire Curve
  • ASTM E119
  • User-calculated Eurocode curves

Compare Curves

• Comparing different curves with importing csv files.

💾 Export Options

• Export fire data to .csv, .txt, .html, or .elf (custom save file)
• Save full report packages including screenshots and comparison charts

💡 Technical Highlights

• Eurocode Fire Curve classification:
  🔹 Ventilation-Controlled vs. 🔸 Fuel-Controlled
  is determined dynamically via t_max comparison with limiting time.

• Curve behavior includes:

  • Heating and cooling phases with time-dependent decay
  • Accurate maximum temperature calculation (t_max_2, t_max_3, etc.)

• Tooltip and GraphMouseMove for real-time point inspection

🔍 Future Enhancements

• Integration with LiveCharts or OxyPlot for advanced graphing
• SQLite-based material & ROFI persistence
• Multi-language support
• Advanced export templates (PDF)
