The seal material is (Elastomer, non-linear material). Before shaft displacement, the hydraulic seal is in prestress condition (or in a pre-compressed state). I am not getting how to model this (precompression) in a static structural system.<\/p>\n<p>Do i simulate pre-compression in system A&nbsp; and then connect system A with system B. If its OK then how do i connect it?&nbsp;<\/p>\n<p>The correct sequence of operation is as follows: 1. Initially seal gets fitted into the hub. This makes seal pre-compressed. 2.
