Define vector perturbations for shape optimization
We need vectors we can manipulate to change the shape of the model during
optimization. For each fillet we will create the following vectors:
Vectors that pull the top fillet (design variable 1) in the x-direction, z-direction and the x-translation direction
Vectors that pull the bottom fillet (design variable 2) in the x-direction, z-direction and the z-translation direction
1.Change from desvar to perturbations.
2.Double-click desvar and select V1.
3.If nodes isn??t already active, click it.
4.In the top fillet select the base node as shown in Figure 2-5.
