Hi all,<\/p>\n

I would like to ask about the values generated by XY plots (Results >> Plots >> XY Plot). I am hoping to output the time-averaged velocities (Unsteady Statistics >> Mean Velocity Magnitude on numerous lines) of certain regions of the geometry, but the values SEEM to be relative but not absolute. I am wondering if there is a way to make them absolute.<\/p>\n

Imagine a cylinder, where the outer part (let’s say radius > 3) is stationary domain and the inner (radius <=3) is the rotational. I am defining it’s speed through Setup >> Cell Zone Conditions >> Fluids >> #name of the domain >> Mesh Motion >> define an absolute rotational speed. If it helps, I attached a picture of it. The orange part is stationary, green is the rotating part, and the vaccum at the center represents a rotor where no fluid passes through.<\/p>\n

<\/p>\n

The trouble I am having now is that the velocities output by the fluids rotating region is very close to zero, making it convincingly like the RELATIVE velocity to the spinning rotor. A strong point to back up this claim is that the velocity output in stationary regions behave differently, having single-digit % error (with values of 5 to 8 m\/s) while the problematic regions have nearly -100% (which means close to zero).<\/p>\n

I would like to see if anyone knows any set up that fixes this, making the output of XY plots be ABSOLUTE, for the sake of post-processing. It would be very complicated to manually fix all those values in Excel since v=rw and at every solution location there is a different r value (Im trying to output v instead of w). I have scanned through the obvious ones but had no findings.<\/p>\n

Thanks a lot!<\/p>\n","protected":false},"template":"","class_list":["post-235065","topic","type-topic","status-closed","hentry","topic-tag-fluent-ansys-1","topic-tag-fluent-cfd-ansys-1","topic-tag-fluid-flow","topic-tag-modeling-setup-advice-2","topic-tag-plotting-results","topic-tag-sliding-mesh","topic-tag-xy-plot"],"aioseo_notices":[],"aioseo_head":"\n\t\t\n\t\n\t\n\t\n\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t
