I am using Ansys Discovery to model a tank with 3 agitators, 2 of the agitators are at the top of the tank and their diameters are about 1\/8th of the diameter of the tank. The 3rd agitator is at the bottom of the tank and the diameter is 15\/16th of the diameter of the tank. I have gravity enabled with only the small agitators are rotating and everything looks good but when I enable the larger agitator it gives me an error that the rotating fluid zone is not alligned with gravity. The agitators are all rotating aroung the y-axis, and gravity is specified in the -Y direction.<\/p>\n
I was wondering if the size of the larger agitator could be causing the error, since it’s weird that the small agitators work fine with and without gravity, while the larger one only works if I turn off gravity. Any insight into this issue would be much appreciated, as I’ve done a fair bit of internet searching but can’t find much about this problem.<\/p>\n","protected":false},"template":"","class_list":["post-360311","topic","type-topic","status-closed","hentry","topic-tag-ansys-discovery","topic-tag-gravity-1","topic-tag-rotating-domain"],"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
