2D Element Analysis

The Animation Settings dialog box allows the parameters that govern animation to be specified.
The analysis will run for a maximum number of cycles or length of time, checking periodically to see if the out of balance or “residual” forces are smaller than the limits set. If they are the model is said to have converged and the analysis stops.
The content of a Graphic view can be set either in:
The Contour Settings dialog box allows the parameters that govern the display of contours to be specified.
The relaxation solution is iterative, and these parameters control the iterative process. They can be adjusted if convergence problems are experienced, or to speed up analysis.
Custom output views allow the user to display any combination of attributes and results in one table (i.e. mix and match from section properties and steel designer results in one table). Custom output views are saved as a template with GSA files. This enables refreshed results and properties under the specified headers each time the view is opened. For now, this view type is limited to nodes and 1D members only.
The Deformation settings dialog box allows the parameters that govern the drawing of the deformed image to be specified.
The Diagram settings dialog box allows the parameters that govern the display of diagrams to be specified.
Both the modal dynamic analysis and buckling analysis make use of an eigensolver. These are iterative so it is useful to be able control the solution procedure.

The Orientation settings dialog box allows the orientation, projection and associated data to be explicitly specified. There are many higher level operations that modify these settings indirectly.
All of the settings that specify the content of an Output view can be set either in the Output settings dialog box or in the dialog boxes accessible from this. The Output settings dialog box can be accessed by going to Output > Output Settings (Ctrl+W) or via the Wizard command on the Data Options toolbar.

There are times when it may be difficult to achieve convergence, particularly where the soil stiffness varies significantly over the site. Adjusting the damping and stiffness parameters may help achieve convergence.
GSA can calculate a large range of results. However not all these results may be required so this allows for selection of particular results to be stored. For an explicit solver these can be selected separately for Full Model Results and for Selected Model Results

The Saved Image Settings dialog box allows the parameters that govern the output of graphic images to be specified.
The Shade surfaces command adjusts the shade of colour filled surfaces according to the current lighting settings. The incidence of the light on the surface, the brightness and the level of ambient light all effect the shading.
For many of the solver options GSA uses a matrix solver. There are a number of options which allow adjustments to be made to the assembly of the stiffness matrix.
The Unwrap option in graphic views projects the displayed structure onto the surface of a cylinder or cone and then unwraps the surface to produce a planar representation of the structure. The unwrapped image can be adorned with labels, diagrams, contours, annotation, and can be generally manipulated in the same way as the normal (wrapped) image.
The Wizard: Output settings dialog box allows the parameters that govern the format and content of output views to be specified. All Output view settings can be specified either in this Output settings dialog box or in dialog boxes accessible from this.
