I defined two computational domain here one is of cylindrical shape and another one is of rectangular shape. Here VAWT is located inside the cylindrical domain and both are located inside the rectangular domain. Right now while doing setup I provided proper dynamic meshing with physical parameters like mass and MOI. Along with that I correctly defined various dynamic mesh zones as stationary and rigid body then also I am getting wrong results. As mentioned in the below picture the cylindrical computational domain was shifting its axis of rotation. I follwed standard path then also this error is happenening again and again. &lt;\/p&gt;&lt;p&gt;Please help me to resolve this issue.&lt;\/p&gt;&lt;p&gt; &lt;\/p&gt;&lt;p&gt;<img decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2024\/11\/06-11-2024-1730891994-Annotation 2024-10-25 125014.png\" alt=\"\" \/>&lt;\/p&gt;&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-392952","topic","type-topic","status-publish","hentry","topic-tag-fluent-cfd-ansys-1","topic-tag-ansys-fluent","topic-tag-Ansysfluentsetuperror-1","topic-tag-ansys-fluent-solver-2","topic-tag-computational-fluid","topic-tag-dynamic-mesh","topic-tag-fluid-domain-1","topic-tag-fluidflowfluent-1","topic-tag-vawt-analysis-1","topic-tag-wind-turbine"],"aioseo_notices":[],"aioseo_head":"\n\t\t<!-- All in One SEO 4.9.10 - aioseo.com -->\n\t<meta name=\"description\" content=\"Hello Team,I am facing an issue while performing transient flow analysis of VAWT.
