Created in the 70&rsquo;s, the ONERA M6 wing serves to validate numerical methods of simulation flows. The wing will be subjected to 0.8395 Mach, 460 degrees Rankine and rotated 3.06 degrees, which should produce a Reynolds number of 11.72 million at the inlet. The equations below show how the Mach number was converted to a velocity, which was used as the inlet velocity.<\/p>\n<p><img decoding=\"async\" class=\"alignnone size-full wp-image-156969\" src=\"\/knowledge\/wp-content\/uploads\/sites\/4\/2022\/08\/hg85.png\" sizes=\"(max-width: 293px) 100vw, 293px\" srcset=\"\/knowledge\/wp-content\/uploads\/sites\/4\/2022\/08\/hg85.png 293w, \/knowledge\/wp-content\/uploads\/sites\/4\/2022\/08\/hg85-50x15.png 50w, \/knowledge\/wp-content\/uploads\/sites\/4\/2022\/08\/hg85-100x31.png 100w, \/knowledge\/wp-content\/uploads\/sites\/4\/2022\/08\/hg85-24x7.png 24w, \/knowledge\/wp-content\/uploads\/sites\/4\/2022\/08\/hg85-36x11.png 36w, \/knowledge\/wp-content\/uploads\/sites\/4\/2022\/08\/hg85-48x15.png 48w\" alt=\" width=\"293\" height=\"90\" loading=\"lazy\" \/><\/p>\n<p><img decoding=\"async\" class=\"alignnone size-full wp-image-156974\" src=\"\/knowledge\/wp-content\/uploads\/sites\/4\/2022\/08\/hg84.png\" sizes=\"(max-width: 500px) 100vw, 500px\" srcset=\"\/knowledge\/wp-content\/uploads\/sites\/4\/2022\/08\/hg84.png 500w, \/knowledge\/wp-content\/uploads\/sites\/4\/2022\/08\/hg84-300x222.png 300w, \/knowledge\/wp-content\/uploads\/sites\/4\/2022\/08\/hg84-50x37.png 50w, \/knowledge\/wp-content\/uploads\/sites\/4\/2022\/08\/hg84-100x74.png 100w, \/knowledge\/wp-content\/uploads\/sites\/4\/2022\/08\/hg84-24x18.png 24w, \/knowledge\/wp-content\/uploads\/sites\/4\/2022\/08\/hg84-36x27.png 36w, \/knowledge\/wp-content\/uploads\/sites\/4\/2022\/08\/hg84-48x36.png 48w\" alt=\" width=\"500\" height=\"370\" loading=\"lazy\" \/><\/p>\n<p>The M6 wing in the ONERA S2MA wind tunnel<\/p>\n<hr \/>\n<h4 content_id=\"geometryamp-mesh\" class=\"toc__permalink\" content_id=\"geometryamp-mesh\" class=\"toc__permalink\"  id=\"GEOMETRY-MESH\">Geometry&nbsp;&amp; Mesh<\/h4>\n<p>&nbsp;<\/p>\n<p><a style=\"color:#1E6DDC;font-weight:bold;text-decoration:none;\"  href=\"https:\/\/ansys13.ansys.com\/KnowledgeArticles\/Discovery\/OneraM6Geometry.zip\" download>Download the file here<\/a><\/p>\n<p>In this video, you will learn&nbsp;how to import the geometry, perform required geometry operations in Discovery AIM and how to generate&nbsp;mesh in the computational fluid domain.<\/p>\n<p><iframe class=\"vidyard_iframe\" src=\"\/\/play.vidyard.com\/FrD7W86TPcZE7nhyHLNH9e.html\" width=\"700\" height=\"400\" frameborder=\"0\" scrolling=\"no\" allowfullscreen=\"allowfullscreen\" loading=\"lazy\"><\/iframe><\/p>\n<p>&nbsp;<\/p>\n<hr \/>\n<h4 content_id=\"physics-setup\" class=\"toc__permalink\" content_id=\"physics-setup\" class=\"toc__permalink\"  id=\"PHYSICS-SETUP\">Physics Setup<\/h4>\n<p>In this video, you will learn how to specify fluid flow conditions.<\/p>\n<p><iframe class=\"vidyard_iframe\" src=\"\/\/play.vidyard.com\/spyr7gWza7Nh2cZ8oGikfL.html\" width=\"700\" height=\"400\" frameborder=\"0\" scrolling=\"no\" allowfullscreen=\"allowfullscreen\" loading=\"lazy\"><\/iframe><\/p>\n<p>&nbsp;<\/p>\n<hr \/>\n<h4 content_id=\"results-evaluation\" class=\"toc__permalink\" content_id=\"results-evaluation\" class=\"toc__permalink\"  id=\"RESULTS-EVALUATION\">Results Evaluation<\/h4>\n<p>In this video, you will learn how to evaluate velocity vectors and Pressure contour&nbsp;in the flow domain.<\/p>\n<p><iframe class=\"vidyard_iframe\" src=\"\/\/play.vidyard.com\/Ccz6PPy6DwiKBfNTRx7Ejn.html\" width=\"700\" height=\"400\" frameborder=\"0\" scrolling=\"no\" allowfullscreen=\"allowfullscreen\" loading=\"lazy\"><\/iframe><\/p>\n<hr \/>\n<h4 content_id=\"verification\" class=\"toc__permalink\" content_id=\"verification\" class=\"toc__permalink\"  id=\"VERIFICATION\">Verification<\/h4>\n<p>This tutorial will utilize NASA&rsquo;s extensive study of the ONERA M6 wing using.

The differences are due to the NASA mesh having a much higher resolution, with more than twice as many nodes and boundary layers as the AIM mesh. Refinement of the AIM mesh can be done to improve the correlation.<\/p>\n<hr \/>\n<p><strong>References<\/strong><\/p>\n<p>Gaultier, Sylvain. &ldquo;L&rsquo;aile ONERA-M6, Star De La CFD.&rdquo; ONERA &ndash; L&rsquo;aile ONERA-M6, Star De La CFD.
