Sintavia has dramatically reduced the design and validation of a 3D printed aerospace heat exchanger from several months to two weeks by integrating NVIDIA’s RTX PRO 6000 Blackwell Workstation.
The aerospace metal additive manufacturing (AM) specialist used the GPU to design and simulate the complex component, which benefits from a 30% reduction in weight and 20% improvement in thermal efficiency. It was validated using in-house CT scanning and downstream thermal/flow testing.
Jose Troitino, Principal Design Engineer at Sintavia says the part demonstrates how Sintavia is "pioneering a new era of thermal management with solutions that are lighter, stronger, and engineered for the most demanding environments."
Requiring an intensive compute- and memory-bandwidth workload, the NVIDIA Blackwell architecture was deployed alongside Siemens Simcenter STAR-CCM+ computational fluid dynamics (CFD) software, which simulates products operating under real world conditions, and nTop's implicit modelling software, to quickly make adjustments without sacrificing fidelity or safety.
Troitino commented, “Because we operate in a fully digital environment—from simulation, through manufacturing and inspection—we are always looking at faster and more efficient solutions to reduce span time at each step. We are very proud that we have been able to do so alongside NVIDIA, Siemens, and nTop.”
According to a press release, Sintavia’s says NVIDIA's Blackwell GPU ran a 30 million-cell Simcenter STAR-CCM+ conjugate heat transfer simulation with over 300 iterations in just seven minutes. For comparison, Sintavia says that works out 11 times faster than the same simulation on a 24-core CPU (coming in at 88 minutes), and resulted in a fully optimised, 3D printable heat exchanger the next day.
