I also set the interaction between the inner surface of the crimping head and the stent as frictionless. However, I encountered an issue where normal displacement could not be activated on the inner rigid body surface.&nbsp;To address this, I used a remote displacement with rigid behavior and tried changing the global coordinate system to the created cylindrical coordinate system which is not working. Even, cylindrical support does not work on the rigid body&#8217;s face.&lt;\/p&gt;&lt;p&gt;<img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2024\/09\/19-09-2024-1726727771-mceclip0.png\" width=\"868\" height=\"342\" \/><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2024\/09\/19-09-2024-1726727901-Capture5.PNG\" alt=\"\" width=\"990\" height=\"661\" \/>&lt;\/p&gt;&lt;p&gt;<img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2024\/09\/19-09-2024-1726727801-mceclip1.png\" width=\"1232\" height=\"569\" \/>&lt;\/p&gt;&lt;p&gt;<img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2024\/09\/19-09-2024-1726727961-Capture3.PNG\" alt=\"\" width=\"1466\" height=\"655\" \/>&lt;\/p&gt;&lt;p&gt;Could you please advise on how to correctly input the radial displacement boundary condition on the rigid body in this scenario? \ud83d\ude4f&lt;\/p&gt;&lt;p&gt;Thank you in advance for your assistance.&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-383090","topic","type-topic","status-publish","hentry","topic-tag-cardiovascular_stent-1","topic-tag-displacementcondition-1","topic-tag-rigid-body"],"aioseo_notices":[],"aioseo_head":"\n\t\t<!-- All in One SEO 4.9.10 - aioseo.com -->\n\t<meta name=\"description\" content=\"Hi there,I am currently working on a self-expansion simulation of a vascular stent and following these steps:In this simulation, a crimper compresses the tubular stent into a smaller diameter.
