Dynamic Simulation of Energy Systems
Create system models for heating and energy systems
With this online tool, you can create and analyze dynamic models for heating, heat, and energy systems. Thermodynamic processes, hydraulics, control, and thermal storage can be considered together to simulate the behavior of complete systems under real operating conditions.
The tool supports engineers, energy consultants, planners, and building technicians in planning, optimizing, and evaluating modern energy systems. The open-source OpenModelica framework is used for modeling.
What is the simulation used for?
Dynamic system simulations make it possible to examine time-dependent processes that cannot be described sufficiently by steady-state calculations. This makes it possible to evaluate control strategies, load changes, storage behavior, and the interaction of various components during planning.
Typical applications:
- Heating systems
- Heat pump systems
- District heating and local heating
- Buffer tanks
- Hydraulic systems
- Control engineering
- Industrial processes
- Research and development
Which simulations are available?
- Thermodynamics
- Hydraulics
- Control
- Storage
- Heat pumps
- District heating
- Dynamic processes
How does the modeling work?
- Upload a system model or choose a demo model
- Define calculation and simulation options
- Start simulation
- Analyze the results
- Download the report as JSON
The simulation provides important metrics for planning, evaluating, and optimizing complex heating and energy systems.

Privacy and data processing
For the simulation, the model file is temporarily transferred to the server, processed, and automatically deleted after completion. The data is used exclusively to perform the simulation and create the analysis report.
