What's In this manual 2. Typographical Conventions Used In This Manual 1. What's In This manual The ansys fluent Workbench tutorial guide contains a number of tutorials that teach you how to use ANSYS Fluent to solve different types of problems 2. Typographical Conventions Used In This Manual Several typographical conventions are used in this manual's text to help you find commands in the user interface Different type styles are used to indicate graphical user interface items and text interface items. For example Iso-Surface dialog box surface/iso-surface text command The text interface type style is also used when illustrating exactly what appears on the screen to distinguish it from the narrative text. In this context, user inputs are typically shown in boldface. For example, solve/initialize/set-fmg-initialization Customize your fmg initialization set the number of multigrid - evels [51 set fmg oarameters on levels residual reduction on level 1 is: [0.001 number of cycles on level 1 is: [101 residual reduction on level 2 is: [0.001 number of cycles on level 2 i [50]100 Mini flow charts are used to guide you through the ribbon or the tree, leading you to a specific option, dialog box, or task page. The following tables list the meaning of each symbol in the mini flow charts Table 1: Mini Flow Chart Symbol Descriptions Symbol Indicated action Look at the ribbon Look at the tree Double-click to open task page Select from task page 可 Right-click the preceding item For example, Release 19.2@ANSYS, nc.
