You can do these steps in CAD software like Ansys Discovery.&lt;\/p&gt;&lt;p&gt;For the contact pairs, you need to only select the surfaces where you expect a contact to occur. For example, you can select the outer face of the sphere as &#8220;Target&#8221; and then select one face of the cube where it contacts with the sphere as the &#8220;Contact&#8221;.&nbsp; &nbsp;&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-355455","reply","type-reply","status-publish","hentry"],"aioseo_notices":[],"aioseo_head":"\n\t\t<!-- All in One SEO 4.9.10 - aioseo.com -->\n\t<meta name=\"description\" content=\"Thanks Shreyas.Here are a couple of suggestions:The two bodies appear to be interfering with each other.
