In 2000, a supersonic Concorde airliner crashed five minutes after taking off from Charles de Gaulle Airport in Paris. The investigation revealed that the cause of the crash was a 42 cm-long metal piece, which had fallen from the preceding aircraft onto the runway. To ensure this tragedy will not happen again, Hitachi Kokusai Electric participated in a government project to develop millimeter-wave radars for detecting foreign objects on runways,using Ansys HFSS and Ansys Cloud.
Hitachi Kokusai Electric determined that, given the electrical size of the problem, the most effective solver technologies in the HFSS portfolio for this analysis were the HFSS-IE method of movements-based solver and the asymptotic capabilities of the SBR+ solver, which can handle large models very effectively. HFSS provides multiple solvers for a range of analysis scales in an integrated user interface, allowing for use of different solvers for different analysis purposes. The study was run on an H16mr virtual machine of Microsoft Azure, featuring 16 Intel Xeon E5 2667 v3 processor cores.
Ansys Cloud was 20 times faster than on-premise simulation (10 hours over 8.5 days)
This work was partly supported by the government project “Research and development of advanced radio frequency spectrum” from the Ministry of Internal Affairs and Communications (MIC) of Japan.
