Introduction This section provides an overview of the BladeGen software and User's Guide. The following topics are covered: What is BladeGen? What's New? System Requirements Special Typefaces Used in This Guide Using On-Line Help Getting Help What is BladeGen? BladeGen is a component of ANSYS BladeModeler. The BladeModeler software is a specialized, easy-to-use tool for the rapid 3-D design of rotating machinery components. Incorporating ANSYS, Inc’s extensive turbomachinery expertise into a user-friendly graphical environment, the software can be used to design axial, mixed-flow and radial blade components in applications such as pumps, compressors, fans, blowers, turbines, expanders, turbochargers, inducers and others. BladeModeler provides the essential link between blade design and advanced simulation including computational fluid dynamics and stress analyses. BladeModeler contains a rich set of tools and functions for designing a turbomachinery blade from scratch, using industry-specific tools, workflow, and language that the blade designer expects. With BladeGen, the user can re-design existing blades to achieve new design goals or create completely new blade designs from scratch. When either re-designing or evaluating an existing blade design, BladeGen facilitates the import of blade geometry interactively or through user supplied files. BladeGen allows sculpted or ruled element blades with linear or compound lean leading or trailing edges. Over/Under-Filing can be applied and leading and trailing edge shapes are easily specified as a full radius, an ellipse ratio, or a simple cutoff. BladeModeler represents a pivotal link between blade design, advanced analysis and manufacturing. Used in combination with ANSYS analysis software, users can rapidly evaluate the performance of a component. BladeGen model files can be imported into DesignModeler using the BladeEditor feature. BladeEditor provides a seamless path to both structural and fluid analysis, which enables the user to efficiently transition from preliminary blade design, to full 3-D viscous flow analysis, and finally to the users native CAD system. 4

What's New? BladeGen 12.0 incorporates the following new features:  Vista RTD - a program for radial inflow turbine design. For details, see Vista RTD.  Vista AFD - a program for axial fan design. For details, see Vista AFD. System Requirements BladeGen is a component of ANSYS Workbench. Please check the ANSYS Workbench help on system requirements for more details. Special Typefaces Used in This Guide This help file uses a set of fonts to highlight menu commands, keyboard keycaps, and dialog box buttons. These fonts are detailed below: Menu Item This typeface represents a menu command. For example, "Select the File | Save menu command to save your work". This typeface represents a particular key on the keyboard. For example, "Press Del to erase the character". This typeface represents a dialog or screen button. For example, "Press the OK button to continue". This typeface represents a key word. For example, "The Blade is a splitter". KeyCap Button Key Word 5

Using On-Line Help Context-specific help is available on-line. Help can be obtained by pressing the F1 key or Help | Help Topics menu command. Context-specific help on a menu command is available by pressing Shift-F1 and selecting the menu item. Context-specific help on a dialog box control is available by:  Pressing the "What’s This?" ( and then selecting a control. ) button in the upper left corner of the dialog box Right mouse clicking on a control (for most controls). Pressing the Help button. Hover Help Hover help is provided in most views for additional information on the data being displayed. The bubble is displayed when the user holds the mouse cursor stationary (hovers) over a data point. The bubble is removed when the user clicks a mouse button or moves the mouse over the bubble. The bubble displays various data depending on the view and data. As a minimum, the bubble displays the horizontal and vertical coordinates of the point. Additional information is available in the Graph Views. The table below describes the information which can be displayed.

Program Overview BladeGen breaks the complex, 3-dimensional (3D) geometry of a blade into two or three 2-dimensional (2D) views. The data from these views is used to create the model, one blade's layer at a time. These views, plus an auxiliary view, are simultaneously displayed in the BladeGen window and all views use the same set of zoom and pan keyboard shortcuts and mouse actions.
