How to apply

Create a library of modular components (e.g., pumps, heat exchangers, turbines) using object-oriented principles, where each component has defined inputs, outputs, and internal states, allowing them to be interconnected to simulate various energy system configurations.

Project actions

01When modeling, clearly define the 'state' of each component (e.g., temperature, pressure) and how it changes over time.
02Use object-oriented programming to create reusable 'blocks' for different system components.
