The SOLIDWORKS shell symmetry feature is quite useful when carrying out a simulation of parts that are symmetric. With the shell symmetry fixture, we can carry out simulation on a single symmetric component and replicate the results on the other portions.
We begin by creating a symmetric part, preferably a circular part.
A quarter portion of such a part would look like the one below.
To create symmetry study, we require symmetry fixtures. In order to use this fixture, we will need to create a new static study. Go into the SOLIDWORKS add-ins folder, and enable the SOLIDWORKS simulation add-in. Proceed to the simulation tab and create a new static study.
A window is pulled up under the feature manager tree which lets you define the parameters of the study. First, we choose a material for our part. I went with an alloy steel. Right click on fixtures and select advanced fixtures. Select the two cut faces of the portion as shown.
Click on the green marker to apply the fixtures. Make the outer faces fixed by applying the fixed geometry fixture on these faces.
For the external loading, we apply a gravitational force on the part.
Next, we simply run the simulation study and SOLIDWORKS automatically creates the meshing.
Notice how the part gets displaced. The displacement is characteristic of the part as a whole. The maximum displaces on the portion matches the one on the whole model. Since the quarter portion is much smaller with a far much less number of nodes, they are solved much quicker compared to the larger model hence resulting in a reduction of computational time. This makes simulations much faster to solve, without compromising the result.
