I am trying to create a no penetration contact between two bodies with an initial separation between them in modal acoustics analysis. This is however, very hard to establish because Ansys tries to create the contact based on the initial separation and having a bonded or a no-separation contact would be incorrect in my case. So how do I create contacts between bodies which are far away to begin with but come in contact during the analysis process? This is easily done in static structural but do you guys know how I could do that for modal?<\/p>\n","protected":false},"template":"","class_list":["post-377411","topic","type-topic","status-publish","hentry","topic-tag-Modal_Analysis-1","topic-tag-acousticmodal-1","topic-tag-contact","topic-tag-mechanical"],"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
