Dr Sandy Wright, principal research engineer, Wolfson Unit at the University of Southampton comments in an <a href=\"http:\/\/www.bio-itworld.com\/Press-Release\/OCF-Petascale-Supercomputer-at-University-of-Southampton-enters-TOP500\/\">OCF press release<\/a>. <em>\u201cWe have a worldwide customer base and have worked with the British Cycling Team for the last three Olympic games, as well as working with teams involved in the America\u2019s Cup yacht race. In the past 10 years, Computational Fluid Dynamics (CFD) has become a perfectly valid commercial activity, reducing the need for physical experimentation. CFD gives as good an answer as the wind tunnel, without the need to build models, so you can speed up research whilst reducing costs. Iridis 5 will enable the Wolfson Unit to get more accurate results, whilst looking at more parameters and asking more questions of computational models.\u201d<\/em><br \/>\n<figure id=\"attachment_738\" aria-describedby=\"caption-attachment-738\" style=\"width: 419px\" class=\"wp-caption aligncenter\"><a href=\"http:\/\/generic.wordpress.soton.ac.uk\/maritimeblog\/wp-content\/uploads\/sites\/363\/2018\/02\/Capture2.png\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-738\" src=\"http:\/\/generic.wordpress.soton.ac.uk\/maritimeblog\/wp-content\/uploads\/sites\/363\/2018\/02\/Capture2-300x214.png\" alt=\"\" width=\"419\" height=\"299\" srcset=\"https:\/\/generic.wordpress.soton.ac.uk\/maritimeblog\/wp-content\/uploads\/sites\/363\/2018\/02\/Capture2-300x214.png 300w, https:\/\/generic.wordpress.soton.ac.uk\/maritimeblog\/wp-content\/uploads\/sites\/363\/2018\/02\/Capture2-768x548.png 768w, https:\/\/generic.wordpress.soton.ac.uk\/maritimeblog\/wp-content\/uploads\/sites\/363\/2018\/02\/Capture2.png 952w\" sizes=\"auto, (max-width: 419px) 100vw, 419px\" \/><\/a><figcaption id=\"caption-attachment-738\" class=\"wp-caption-text\">Scale up of standard CFD testcase KVLCC on Iridis 4 upto 2048 cores<\/figcaption><\/figure><br \/>\nPhD students in FSI are alo important users of the Iridis computers.
