Cloud-Based Simulation Helps PC Manufacturer Bolster Design Testing

Running SimScale’s conjugate heat transfer simulation in the cloud helped OnLogic meet thermal performance requirements for computer systems.

MUNICH–SimScale, the provider of a production-ready SaaS application for engineering simulation, reported that the industrial PC company OnLogic has integrated the cloud-based simulation platform into its design testing process. By running conjugate heat transfer simulations in the cloud, the OnLogic team was able to make quick design iterations in parallel and reach efficiency targets, while saving tens of thousands of dollars in materials costs, according to a release from SimScale.

For the design of a high-performance rugged PC (Karbon 700), OnLogic had stricter thermal requirements than ever before. Simulation methods had proven to be valuable in previous product developments, and using the technology was clearly a must. This particular project, however, added a time constraint, and the team needed to find a solution that would allow them to make quick design iterations and achieve the best possible thermal performance.

Using cloud-based simulation with SimScale, OnLogic managed to tackle these challenges, as well as collaborate effectively and save on in-house computing needs. With conjugate heat transfer simulations run in parallel in the cloud, the team tested multiple heat sources and evaluated the thermal performance of their chassis in a low-airflow environment.

“Our overall impression of working with SimScale on our project is two thumbs way up,” said Erick Kopff, engineer at OnLogic, in the release. “We’re already using it on new projects, and expect SimScale to be part of all future product developments.”

Final results were reported to show 95 percent accuracy of the actual product testing performance. This enabled OnLogic to implement a design feature that gave the team the required thermal results but saved significant manufacturing costs by using less material. With a $3 per-system cost saving on thousands of units, OnLogic reportedly saved tens of thousands of dollars in materials costs, including adjustments to chassis extrusions and cooling solutions.

Based in Munich and Boston, SimScale ( offers what is said to be the first production-ready SaaS application for simulation. The company said that it provides instant access to computational fluid dynamics (CFD) and finite element analysis (FEA) to more than 150,000 users, moving high-fidelity engineering simulation technology from a complex and cost-prohibitive desktop application to a user-friendly web application accessible via a pay-as-you-go pricing model.

OnLogic ( is a global industrial PC manufacturer that focuses on hardware for the IoT edge. Founded in 2003 as Logic Supply, OnLogic designs highly-configurable computers engineered for reliability. Its systems are designed to operate in the harshest environments and power innovation in the evolving Internet of Things. The company’s direct-to-customer business model is said to combine vertical integration, modular product design, and a powerful online platform.

OnLogic is based in South Burlington, Vermont.
