Because you always want to prove a theoretical situation and compare to computer generated results.&nbsp;<\/p>\n<p>I never got paid to perform analysis on a plate, beam or bar, but I used them all the time to prove my concept and that my analysis was going in the right direction and made sense.&nbsp; In other words, you just can&#8217;t take the computer result and run.&nbsp; Most of the time, the simple plate found issues with units, boundary conditions, and significant digits. &nbsp;Of course, this was in the stone age when engineers wrote their own finite element programs in Fortran (ancient language)&nbsp;<\/p>\n<p>But now SolidWorks makes it easy to look at the NAFEMS examples and create the simple 3D&nbsp;CAD&nbsp;models used in the process.&nbsp; In this example, located in Help&gt;Simulation Tutorials.NAFEMS&gt;Themal&gt;Steady State Temperature Distribution in a Plate you will see two examples.&nbsp; The first boundary condition is set on the left edge with Temperature =1000C.&nbsp; The other three edges are set to 0C.&nbsp;<\/p>\n<p><a style=\"display: inline;\" href=\"https:\/\/blog-assets.solidworks.com\/uploads\/sites\/3\/6a00d83451706569e20154342c0d1a970c.jpg\"><img decoding=\"async\" class=\"asset  asset-image at-xid-6a00d83451706569e20154342c0d1a970c\" title=\"NAFEMS Steady State Temperature Boundary Conditions\" src=\"https:\/\/blog-assets.solidworks.com\/uploads\/sites\/3\/6a00d83451706569e20154342c0d1a970c-800wi.jpg\" border=\"0\" alt=\"NAFEMS Steady State Temperature Boundary Conditions\" \/><\/a>&nbsp;<br \/>In SolidWorks, select &nbsp;Insert, Surface, Planar, and create a 400mm x 600mm rectangle.&nbsp;&nbsp;Then add construction lines with horizontal and vertical construction lines at (0,200)and (200, 0), (300, 0).&nbsp;
