And yet simulation can only bring value if it models that complexity and if at the same time engineers can do simulations quickly enough to influence design. Hence, to keep the competitive edge, companies need to equip their simulation engineers with CFD software that delivers high-fidelity physics models, smart simulation techniques and fast meshing technologies.<\/p>\n\n\n\n<p>With this mission in mind, Simcenter&nbsp;STAR-CCM+ 2021.2 delivers new features across the entire simulation workflow&nbsp;to help&nbsp;you engineer innovative and better performing products, faster &#8211; from hyper-sonic spacecrafts to life-saving heart-valves.<\/p>\n\n\n\n<p class=\"has-text-color has-background has-large-font-size\" style=\"color:#ffffff;background-color:#009999\"><strong><a href=\"https:\/\/support.sw.siemens.com\/en-US\/product\/226870983\" target=\"_blank\" rel=\"noreferrer noopener\">To download Simcenter STAR-CCM+ 2021.2, please visit the Support Center<\/a><\/strong><\/p>\n\n\n\n<div style=\"height:58px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h3 class=\"wp-block-heading has-text-color\" style=\"color:#009999\">Higher accuracy for hypersonic applications<\/h3>\n\n\n\n<p>Hypersonic vehicle design&nbsp;requires&nbsp;accurate prediction of&nbsp;bow shocks&nbsp;and surface heating, a challenge for&nbsp;CFD codes&nbsp;due to the carbuncle effect.&nbsp;Improvements in&nbsp;Simcenter&nbsp;STAR-CCM+&nbsp;2021.2&nbsp;mitigate this&nbsp;effect&nbsp;to deliver better&nbsp;convergence and realistic temperature predictions,&nbsp;giving&nbsp;you&nbsp;higher&nbsp;confidence&nbsp;in your&nbsp;simulation results.&nbsp;<\/p>\n\n\n\n<figure class=\"wp-block-video aligncenter\"><video controls poster=\"https:\/\/blogs.sw.siemens.com\/wp-content\/uploads\/sites\/6\/2021\/06\/CCM20212_ApolloReentry.png\" src=\"https:\/\/videos.mentor-cdn.com\/mgc\/videos\/5400\/70d160f8-2e10-475a-a689-b7182dc5b53b-en-US-video.mp4\"><\/video><figcaption class=\"wp-element-caption\">Mitigating the carbuncle effect for surface heat-up of the Apollo capsule during hypersonic reentry <\/figcaption><\/figure>\n\n\n\n<p class=\"has-text-color has-background\" style=\"color:#ffffff;background-color:#009999\"><a style=\"\" href=\"https:\/\/blogs.sw.siemens.com\/simcenter\/mitigating-the-carbuncle-effect-for-hypersonic-cfd-simulations\/\" target=\"_blank\" rel=\"noreferrer noopener\"><b>Learn more about hypersonic <\/b><\/a><strong><a href=\"https:\/\/blogs.sw.siemens.com\/simcenter\/mitigating-the-carbuncle-effect-for-hypersonic-cfd-simulations\/\" target=\"_blank\" rel=\"noreferrer noopener\">simulations in Simcenter STAR-CCM+  <\/a><\/strong><\/p>\n\n\n\n<hr class=\"wp-block-separator has-css-opacity\"\/>\n\n\n\n<div style=\"height:58px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h3 class=\"wp-block-heading has-text-color\" style=\"color:#009999\"><strong><strong>Faster industrial multiphase simulations<\/strong><\/strong><\/h3>\n\n\n\n<p>Accuracy and computational efficiency are&nbsp;often&nbsp;competing goals&nbsp;for multiphase simulations.&nbsp;With our&nbsp;hybrid multiphase approach, coupled with adaptive mesh refinement, you&nbsp;don\u2019t&nbsp;have to&nbsp;compromise on either.
