🏔️ Description

Cairn is a simulation and optimization software for energy and environmental systems. It allows for the modeling of technical components and the simulation of their behavior in various scenarios. Cairn is designed to be used in research and engineering environments to evaluate the environmental and economic impacts of energy systems. 🌍🔍 Cairn is developped by the CEA-Liten in Grenoble and Chambéry.

🌟Features

• 🛠️ Modeling of technical components.
• ⚡ Simulation of energy scenarios.
• 🌳 Evaluation of environmental impacts.
• 📈 Optimization of system configurations, sizing and management.
• 🖥️ Graphical user interface for configuration and visualization of results.
