PASS/NOZZLE-FEM 3.5. Program Manual

3.12. Postprocessor

Dialog box for the results view allows you to interactively view the results, obtained during the calculation of the deflected mode due to action given the forces and pressure (fig. 3.80).

The window is opened by pressing the 3D button located under each drawing of the model, in the tab "Calculation results".

The main function of the postprocessor is to view the results of finite element analysis (FEA): displacements, stresses, and user-specified loads.

3.12.1. View displacement contours

To view displacements or rotation angles at the structure points, select "Displacement..." item in the corresponding toolbar dropdown list, as shown in fig. 3.81.

3.12.2. View stress contours

To view stresses at the structure points, select "Stress..." item in the corresponding toolbar dropdown list, as shown in fig. 3.82.

3.12.3. View boundary conditions and loads

To view user defined loads, select one of the items in the corresponding toolbar dropdown list: surface or body forces. Surface forces (pressure) can be displayed as contours or arrows applied perpendicular to the loaded finite element surface (fig. 3.83).

Another way to display boundary conditions and loads is to use the toolbar command, which allows you to choose what to display as well as set display options (fig. 3.84).
