]]> 3x Speed Improvement of a CFD Solver https://nag.com/webinars/3x-speed-improvement-of-a-cfd-solver/ Thu, 17 Aug 2023 13:54:45 +0000 https://nag.com/?post_type=webinars&p=3540 This webinar covers: that the POP project and Zenotech undertook to investigate the performance of zCFD. An initial Performance Audit using Intel's VTune Amplifier performance profiler identified several areas of potential improvement, which Zenotech went on to address in a POP Proof-of-Concept (PoC) study. As a result of the PoC, zCFD ran 3x faster on a representative input case.
