As 3D printers get larger and geometry gets more complex, simulation requirements increase — and with that, the need for ever higher computing power. Oqton solved this bottleneck without compromising on accuracy. This article presents a heat exchanger simulation that proves it is possible to simulate massive complexity with high precision on a standard workstation.
Oqton validated its simulation engine on a "gold standard" of complexity: a massive heat exchanger featuring high-density intensification geometry and ultra-thin walls.
Traditional tools often struggle here, producing jagged, inaccurate meshes on such fine features. Engineers are frequently forced to offload to expensive dedicated servers just to succeed.
Oqton's approach uses a "Zero Simplification" mindset — combining the Simulation Engine with 3DXpert's hybrid geometrical kernel, which seamlessly integrates B-Rep, Mesh, Lattice Beams, and Implicit geometries.
This architecture projects the simulation mesh directly onto the high-fidelity CAD surface, capturing the exact shape of 0.7mm walls where features are finer than the element size. The non-linear mechanical simulation accurately captures the plastic behavior of AlSi10Mg, while the thermal simulation explicitly considers the surrounding powder bed.
Processing 2.9 million elements in just 8 hours 15 minutes on a standard workstation.
Model extended to 6.7 million elements including surrounding powder bed, simulating
the full thermal history of a 60µm process triple laser 30-hour print.
This simulation confirmed that the heat exchanger is fully ready for production. Thermal stability was verified to ensure process safety, and complex deformations were captured to generate an accurate compensated model. This dual validation eliminated the need for physical trial and error.
Oqton empowers engineers to achieve "First-Time-Right" confidence directly from a local workstation, without the hardware bottleneck.
