The air intake starts from inlet then flowing it to the outlet domain through the impeller in the rotor domain. The stator outlet domain has a rectifying grid inside of 4 mm thick. The 12 blades of the impeller are 2 mm thick. The hydraulic diameter of the system is 762 mm and the total length of the whole domain is 9701.325 mm from inlet up to the outlet domain. The boundary condition at the outlet is 0 Pa gauge and the outlet BC is 250 Pa gauge. The impeller speed was set to 2000 RPM. I assigned some surface points 6477 mm from the inlet right after the rectifying grid to measure the dynamic and static pressure at these points. These pitot traverse points were assigned at the following points from positive and negative x and y axis: 0.316, 0.548, 0.707, 0.837, and 0.949 of the radius of the system. I run a simulation using the ansys solution but I am getting high dynamic pressure results at 0.949 point surface then becomes lower at 0.316 point surface instead of the opposite. Only to residuals converged by the way as can be seen with the attached results. The whole domain&#8217;s meshing is also attached and the meshing quality metrics. Why I am not getting the opposite result? Thank you for your help.&lt;\/p&gt;&lt;p&gt;<img decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2024\/11\/24-11-2024-1732406575-IMG_0350.png\" alt=\"\" \/>&lt;\/p&gt;&lt;p&gt;<img decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2024\/11\/24-11-2024-1732406563-IMG_0349.png\" alt=\"\" \/>&lt;\/p&gt;&lt;p&gt;<img decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2024\/11\/24-11-2024-1732406543-IMG_0352.png\" alt=\"\" \/>&lt;\/p&gt;&lt;p&gt;<img decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2024\/11\/24-11-2024-1732406520-IMG_0351.png\" alt=\"\" \/>&lt;\/p&gt;&lt;p&gt;<img decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2024\/11\/23-11-2024-1732406396-IMG_0372.jpeg\" alt=\"\" \/><img decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2024\/11\/23-11-2024-1732406371-IMG_0374.jpeg\" alt=\"\" \/>&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-395069","topic","type-topic","status-publish","hentry"],"aioseo_notices":[],"aioseo_head":"\n\t\t<!-- All in One SEO 4.9.10 - aioseo.com -->\n\t<meta name=\"description\" content=\"I am simulating a system consists of three domains namely stator inlet (stationary zone), rotor domain (rotating zone) and stator outlet (stationary zone).
