Optimize HVAC Designs

CAE for Heating, Air Conditioning and Ventilation Applications

SimScale is a 100% cloud-based CAE software for HVAC simulation that lets you test, validate, and optimize your designs through CFD, heat transfer and thermal analysis.



Staying competitive requires engineers to constantly innovate and find new ways to improve their designs while reducing the development costs and time to market. Computer-aided engineering (CAE), also called engineering simulation, is becoming the industry standard for developing HVAC products better, faster and cheaper. Using cloud-based CAE with SimScale, HVAC engineers worldwide are performing computational fluid dynamics, conjugate heat transfer and thermal analyses for testing and optimization of heating and cooling equipment, air conditioning, ventilation systems and more. The SimScale platform enables you to test several design versions.

HVAC Equipment Optimization

With CAE, you can predict the performance of rotating machinery like industrial fans, vents, compressors, pumps or blowers. In addition, CAE helps to minimize pressure drops across ducts and other components. SimScale can also be used to optimize heating equipment. Everything with one simulation tool, 100% in the web browser.

energy efficiency

Energy Efficiency

Reduce energy consumption for HVAC systems via better heat exchanger designs, ducting, fan or cooling unit placement and get energy efficiency certification for buildings, data centers and equipment. SimScale helps engineers develop products that comply with and exceed current quality standards and regulatory provisions.

cooling and heating

Cooling and Heating

Improve thermal management of machinery, heat sinks or engines. Optimize electronics cooling on all levels (from chip to room), predict resulting temperatures in product’s case, reduce failure risk and decide on fan placement, sizing and speed for cost-efficient cooling.

Thermal comfort

Thermal Comfort

In HVAC system design, it is crucial to ensure optimal thermal comfort for people, whether it’s at home, in the office, a plane or a car. SimScale can help predict thermal comfort by testing different air supply outlets, their placement or number, and evaluating the temperature gradients, air distribution or velocity plots.

contamination control

Contamination Control

Air quality is essential in interior spaces. Use SimScale to ensure a fast and efficient removal of high contaminant concentrations in parking garages, predict smoke propagation for safety control in tunnels or subway stations, develop an intelligent ventilation strategy and optimize cleanroom designs.

wind engineering

Wind Engineering

SimScale is used in wind engineering, to predict wind loads on structures or visualize the effects of new buildings on urban airflow fields. Civil engineers can now use cloud CFD to test architectural designs or reduce contaminant dispersal from industrial facilities, by analyzing environmental flows.

Case Study - IBEEE

Improve the Flow Rate of a Ventiliation System by 40%

IBEEE is a holistic development and engineering service provider for electronic systems and energy concepts for buildings. The company used the SimScale platform to investigate and quantify the performance of the fanless ventilation system used in its passive houses. The simulation showed that the fan could not only be replaced by the stack effect but that this is actually more powerful than the active solution.

Smoke Propagation in a Garage

Reduce smoke propagation in a garage

Almost everyone knows the smell of fumes in a garage. If there are too many fumes in a garage, it soon gets dangerous for your health if you stay in the garage longer than for a few minutes. To avoid this, there is Computer-aided Engineering

I loved the fact that I could do what I need to do in a browser. I started working without installing any software. Using any computer I could upload the model and start the analysis. That was the big “wow” moment.
