General Program Description Pdisp Pressure Induced Displacement Analysis Pdisp calculates the displacements (and stresses if required) within a linear elastic or non-linear soil mass, arising from uniform normal or tangential pressure, applied to rectangular and circular loaded planes. The program is ideal for predicting the displacements that may arise due to the action of several loads in a soil mass. Pdisp is a development of (and replacement for) Vdisp. Vdisp predicted displacements induced by vertical loads on horizontal loaded areas only. Pdisp is capable of predicting displacements due to both vertical and horizontal loads. Components of the User Interface The principal components of Pdisp's user interface are the Gateway, Table Views, Graphical Input, Plan View, Cross Sectional View, 3D Graphical Output, Tabular Output, toolbars, menus and input dialogs. Some of these are illustrated below. This dialog can be accessed by clicking Tools | Preferences. Preferences can be set whether a file is opened or not. The Preferences dialog is accessible by choosing Tools | Preferences from the program's menu. It allows user to modify settings such as numeric format for output, show welcome screen, option for new model wizard, print parameters and company information. These choices are stored in the computer's registry and are therefore associated with the program rather than the data file. All data files will adopt the same choices.
