            axisymmetric loads and support, only a 2-D model, sliced through the 3-D geometry, is
            needed to correctly predict the deformation of or stress in the structure. The figure below
            gives the cross section of an axisymmetric model of a two-tier garden fountain made of
            concrete. Determine the maximum deformation and von Mises stress under the given
            hydrostatic pressure. Use adaptive meshing to improve solution convergence.

                 Solution
                 To solve the problem with ANSYS Workbench, we employ the following steps:

                   Step 1: Start an ANSYS Workbench Project
                   Launch ANSYS Workbench and save the blank project as ‘Fountain.wbpj’.
                   Step 2: Create a Static Structural Analysis System
                   Drag the Static Structural icon from the  Analysis Systems Toolbox window
                     and drop it inside the highlighted green rectangle in the Project Schematic
                     window to create a standalone static structural analysis system.
