You must plan ahead when building a solid model so that it can be used for
realistic finite element load and/or restraint analysis cases. You often do that in
the solid modeling phase by using lines or arcs to partition lines, curves, or
surfaces. This is called using a “split line” in SolidWorks and SW Simulation.
There is also a “split part” feature that is similar except that it cuts a part into
multiple sub-parts. You sometimes need to do that for symmetry or antisymmetry
finite element analysis so that we can analyze the part more
efficiently. Here, the concept of splitting surfaces for mesh control will be
illustrated via stress analysis.
