The Analysis menu

Figure 1. The Analysis

The Analysis menu is used to launch the basic SectionBuilder analysis tasks. To perform analysis tasks, the following step must be completed first.

  1. Open the file describing the problem you want to investigate.

Figure 1 shows the Analysis menu, which gives access to the following commands.

  1. Perform the finite element analysis of the cross-section to generate Saint-Venant's solution
  2. Open the graphical window to view the cross-section geometry

Perform the FE analysis (Analysis→FE Analysis)

Once an input file has been loaded into SectionBuilder, the finite analysis of the cross-section can be performed by invoking command Analysis→FE Analysis. Alternatively, clicking on the FEA icon on the toolbar launches the same task.

Depending on the complexity of the cross-section under investigation and the speed of your computer, the analysis task could be completed in a fraction of a second or in a few minutes. When the analysis is completed, icon FEA is greyed out and icon View Section appears, giving you the signal to proceed.

View the cross-section (Analysis→View Section)

Once the finite element analysis has run to completion, it is time to view the cross-section by invoking command Analysis→View Section. Alternatively, clicking on the View Section icon on the toolbar launches the same task.

Figure 2. The circular section with fins

Once command Analysis→View Section is given, the cross-section under investigation is drawn on the screen. Figure 2 shows a circular section with fins, as an example. SectionBuilder has generated a two-dimensional mesh of the cross-section. Figure 2 shows the following attributes of the mesh.

  1. The elements are shown with thin blue lines, and
  2. The nodes of the elements are depicted as green squares.
