Select &#8220;Radial Impeller&#8221;.&nbsp; Adjust the meridional (z,r) coordinates to reflect your design (or do this later).&nbsp; Accept the initial angle\/thickness values (this can be changed later)&lt;\/p&gt;&lt;p&gt;-In quadrant 3 (i.e. Angle View), RMB inside the window and select &#8220;Beta Definition&#8221; from the pop-up menu.&nbsp; The default curve type is spline.&nbsp; It&#8217;s easier to work with a Bezier curve definition, so RMB in the window again and select &#8220;Convert Points to&#8221;-&gt;&#8221;Bezier Control Points&#8221;.&nbsp; Hit &#8220;OK&#8221; on the Point Count Dialag pop-up window.&lt;\/p&gt;&lt;p&gt;-Note that the beta angle definition is based on the axial direction by default (this can be changed to the tangential direction by going to Model-&gt;Ang\/Thk Beta Definition).&nbsp; Typically, the backsweep angle is based on the tangential direction, so an appropriate angle transformation will need to be made&nbsp;&lt;\/p&gt;&lt;p&gt;-In the Angle View, double click on the first Beta angle point and enter the inlet angle.&nbsp; Double-click on the last Beta angle point and enter the angle representing the backsweep angle.&nbsp;&lt;\/p&gt;&lt;p&gt;Note that this has adjusted the beta angles for the hub layer.&nbsp; The above steps will need to be repeated for all the active layers.&nbsp; The intermediate beta Bezier curve points will then need to be adjusted to provide a consistent theta distribution (or &#8220;blade wrap angle&#8221;) for all layers.&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-391408","reply","type-reply","status-publish","hentry"],"aioseo_notices":[],"acf":[],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/replies\/391408","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/replies"}],"about":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/types\/reply"}],"version-history":[{"count":0,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/replies\/391408\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=391408"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
