We have all used symmetry to boost our simulation times, whether it be planar or cyclic and were happy to have achieved the results in a short time, only to be told by the manager to run the simulation for the full model so it makes more sense to him and to the customers.
Here is a new feature in SolidWorks 2014 which will keep both you and your boss happy. You now have the option to apply the symmetry for the analysis and the software will mirror the results for you and show you the results in the entire model. These new results will actually serve as a double check for the symmetry assumptions that made.
In the PropertyManager of the desired result quantity, under Advanced Options, select Display symmetric results.
Here is a quick look at this feature in action.
