Right-click on Solution (A6) in the Outline tree, and select Solve to update the
model results. The new deformation and stress results are shown below. Both
the maximum deformation and the maximum von Mises stress values are
shown to be slightly increased, as compared to the results considering only the
hydrostatic pressure load.

5.9 Summary

In this chapter, we discussed a few modeling techniques and options related to FEA solu-
tions. For static analysis of symmetrical structures, the symmetry features should be
explored in both the modeling (meshing) stage and the solution stage (if the BCs are sym-
metrical as well). Substructuring or using SEs is a useful technique for solving large-scale
problems with constrained computing resources. Convergence of the FEA solutions is the
important goal in FEA and should be monitored by using the error estimates and employ-
ing the adaptive FEA capabilities in the software. The showcase using ANSYS Workbench is
introduced to show how to apply the various techniques introduced in this chapter.
