Free SolidWorks from Performance Constraints (FSWPC-13-#14)

(Modeling Methodology - Top Level Mates and Flexible Subassemblies)

When an assembly is opened, all of the mates at the top level of the assembly are calculated as well as any mates that are involved in flexible sub-assemblies, you can see this in the AssemblyXpert screen shots below. Solving Subassemblies as Flexible adds a tremendous amount of extra calculations that would not be required if the flexible subs were turned off. In our tests setting our Flexible sub-assemblies to Rigid dropped the number of mates being evaluated at the top level from 1292 to 139.

Also when building your assembly you want to make sure that you structured it in a manner to minimize the need for top level mates. To accomplish having less mate in your top level assembly it involves utilizing more sub-assemblies than individual parts and taking advantage of other assembly features such as patterning components like bolts and screws.

You can by looking at our deltas see that on our Practical machine we gained almost 3.5% total improvement. If we look at the Typical machine we can see that the overall improvement is cut by just over 13% performance gain and took over 37min off of our benchmark time.
