Usually, I click &ldquo;Share for the entire geometry under Workbench&rdquo; option in SpaceClaim to create contacts (as shown in the image below). However, as you explained earlier, I want to ensure I understand the &ldquo;sharing topology&rdquo; part correctly. Do I need to click the &ldquo;Share&rdquo; option component by component, right? Referring to the attached screenshot of the SpaceClaim CAD geometry design tree, I need to keep the &ldquo;Solder Mask 2&rdquo; and &ldquo;PCB Copper Pads&rdquo; components hidden, while leaving the &ldquo;FR4&rdquo; component parts unhidden, and then click the &ldquo;Share Topology&rdquo; option under Workbench. Once this is shared, I unhide the &ldquo;Solder Mask 2&rdquo; components and click the &ldquo;Share&rdquo; button to share bodies within &ldquo;Solder Mask 2&rdquo; and &ldquo;FR4,&rdquo; repeating this process for each component sequentially. Is this what you are suggesting as the correct way?&lt;\/p&gt;&lt;p&gt;Also, I am sharing the screenshot of my boundary conditions just to ensure I have applied them correctly. I will remove the fixed support and add remote displacement, but do I need to make any other changes to the boundary conditions, such as removing or adding any? Please suggest after referring to the screenshots of the boundary conditions attached. I would greatly appreciate your reply.&lt;\/p&gt;&lt;p&gt;&nbsp;&lt;\/p&gt;&lt;p&gt;&nbsp;<img loading=\"lazy\" decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2024\/03\/28-03-2024-1711668609-Share topology.GIF\" alt=\"Share Topology in Space claim\" width=\"1232\" height=\"584\" \/>&lt;\/p&gt;&lt;p&gt;&nbsp;&lt;\/p&gt;&lt;p&gt;<img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2024\/03\/28-03-2024-1711669010-Displacement.GIF\" alt=\"Displacement applied on Symmetry Faces XY Plane\" \/> Displacement Boundary Condition applied on Symmetry Faces XY Plane&lt;\/p&gt;&lt;p&gt;<img loading=\"lazy\" decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2024\/03\/28-03-2024-1711669026-Displacement2.GIF\" alt=\"Displacement applied on Symmetry Faces XY Plane\" width=\"834\" height=\"551\" \/>Displacement Boundary Condition applied on Symmetry Faces YZ Plane&lt;\/p&gt;&lt;p&gt;&nbsp;&lt;\/p&gt;&lt;p&gt;<img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2024\/03\/28-03-2024-1711669132-Thermal Conditon.GIF\" alt=\"Thermal Boundary Condition applied on Entire Geometry\" \/>Thermal Boundary Condition applied on Entire Geometry&lt;\/p&gt;&lt;p&gt;<img loading=\"lazy\" decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2024\/03\/28-03-2024-1711669177-Element Birth and Death.GIF\" alt=\"Element Birth and Death\" width=\"879\" height=\"547\" \/> Element Birth and Death on solder joints&lt;\/p&gt;&lt;p&gt;<img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2024\/03\/28-03-2024-1711669213-Fixed Support.GIF\" alt=\"Fixed Support\" \/>&lt;\/p&gt;&lt;p&gt;Earlier I ussed Fixed Support at this vertex location but I will use remote displacement as per you suggestion.
