1. Insert > Location > Volume. Here lets call it “Volume 1” 2. In the Volume settings specify the following: – the domains to be included by multi-selecting the them in the Domains list – set Method = Sphere – choose a Point at the center of the model – choose a Radius that will encompass the entire model – set Mode = Below Intersection 3. Now, you can calculate the volume average with the expression volumeAve(Pressure)@Volume 1<\/p>\n","protected":false},"template":"","class_list":["post-167145","topic","type-topic","status-publish","hentry","topic-tag-19-2","topic-tag-cfd-post","topic-tag-fluid-dynamics","topic-tag-general","topic-tag-volume-average","topic-tag-volume-integral"],"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
