NVIDIA GPUs accelerate Sintavia aerospace heat exchanger design
NVIDIA, headquartered in Santa Clara, California, USA, has published a case study focused on how aerospace component manufacturer Sintavia, based in Hollywood, Florida, has used GPU-accelerated simulation workflows to develop lightweight heat exchangers for aerospace and defence applications.
According to the report, Sintavia used NVIDIA’s RTX PRO 6000 Blackwell Workstation Edition GPUs in its high-performance workstations and NVIDIA data centre GPUs within its high-performance computing (HPC) clusters to support simulation-driven design. The study noted that the NVIDIA hardware was used alongside CUDA-enabled engineering software from nTop and Siemens, including Siemens’ Simcenter STAR-CCM+.
“Before, we were constrained by compute. Large simulations could take days – even weeks,” stated Jose Troitino, Principal Design Engineer at Sintavia. “With NVIDIA Blackwell GPUs, we have cut runtimes dramatically and scaled to models we never thought possible.”
The NVIDIA RTX PRO 6000 Blackwell Workstation Edition GPU includes 96 GB of GDDR7 memory and 24,064 CUDA cores, enabling simulations that previously
As part of the case study, NVIDIA highlighted a recent project in which Sintavia developed a next-generation heat exchanger for an aerospace customer within two weeks using GPU-accelerated simulation.
The report stated that GPU computing delivered more than eleven times faster results than CPU-based workflows for Simcenter STAR-CCM+ workloads.

In Sintavia’s internal testing, it was reported that a 30 million-cell conjugate heat transfer simulation with more than 300 iterations ran in approximately seven minutes on a Blackwell GPU, compared with eighty-eight minutes on a 24-core AMD 7965WX CPU.
The heat exchanger was additively manufactured as a single component. According to the case study, the design achieved approximately 30% weight reduction and a 20% improvement in thermal efficiency compared to conventional designs.
Sintavia reported that the component’s integrity was validated through in-house computed tomography (CT) inspection and downstream thermal and flow testing.
