The Common options are:
- Auto Save
Select the time between automatic saves.
To turn off automatic saves, set Auto Save to
Never.Note: This option affects more than one CFX product.
- Temporary directory
To set a temporary directory, click Browse
to find a convenient directory where the autosave
feature will save state files.
The following sections describe the options under Common:
The appearance of the user interface can be controlled from the Appearance options. The default user interface style will be set to that of your machine. For example, on Windows, the user interface has a Windows look to it.
Under GUI Style, select the user interface style to use.
For Font and Formatted Font, specify the fonts to use in the application.
Note: It is important not to set the font size too high (over 24 pt. is not recommended) or the dialog boxes might become difficult to read. Setting the font size too small might cause some portions of the text to not be visible on monitors set at low resolutions. It is also important not to set the font to a family such as Webdings, Wingdings, Symbols, or similar type faces, or the dialog boxes become illegible.
Select Enable Threading and set Hardware Capacity Fraction to a value greater than 0 to make use of multiple CPU cores to improve the general performance of applications that share this common setting, at the possible expense of CPU availability for other applications. The maximum allowed value of 1 (default) uses all available CPU cores.
Under System, select the unit system to use. Unit systems are sets of quantity types for mass, length, time, and so on.
The options under System include
SI,CGS,English Engineering,British Technical,US Customary,US Engineering, orCustom. OnlyCustomenables you to redefine a quantity type (for example, to use inches for the dimensions in a file that otherwise used SI units).The most common quantity types appear in the main Options dialog box; to see all quantity types, click .
Select or clear Always convert units to Preferred Units.
If Always convert units to Preferred Units is selected, the units of entered quantities are immediately converted to those set in this dialog box.
For example, if you have set Velocity to
[m s^-1]in this dialog box to make that the preferred velocity unit, and elsewhere you enter20 [mile hr^-1]for a velocity quantity, the entered value is immediately converted and displayed as8.94078 [m s^-1].
The two sets of units are:
The units presented on this dialog box, which control the default units presented in the user interface as well as the units used for mesh transformation.
The solution units. For details, see Setting the Solution Units.
For additional information about units, see Mesh Units.
If you have complicated simulations that feature many overlapping lines, you can specify a Picking Tolerance that will increase the resolution for picking operations. Values must be between 1 (low resolution) and 0 (very high resolution); the default value is 0.1. Note that increasing the resolution will slow printing times.
Select Double Buffering to use two color buffers for improved visualization.
Double Buffering is a feature supported by most OpenGL implementations. It provides two complete color buffers that swap between each other to animate graphics smoothly. If your implementation of OpenGL does not support double buffering, you can clear this check box.
Select or clear Unlimited Zoom.
By default, zoom is restricted to prevent graphics problems related to depth sorting. Selecting Unlimited Zoom allows an unrestricted zoom.
Select or clear Use GPU Rendering for Printing.
If your graphics hardware is compatible with GPU rendering, selecting this preference is strongly recommended.
When selected, this preference causes saved pictures in CFD-Post to use GPU rendering and saved pictures in CFX-Pre and TurboGrid to (by controlling the default value of a setting in the Save Picture dialog box) use GPU rendering by default.
When you save a picture with GPU rendering, your graphics hardware renders an image that closely matches what is shown in the viewer.
If GPU rendering is not set or cannot be used (for example, if compatible GPU hardware is not found), software rendering is used instead. Software rendering is relatively slow and does not always render as shown in the viewer. One benefit of software rendering is that it has no graphics hardware requirements.
Note: Batch mode printing in CFX-Pre and TurboGrid does not support GPU rendering.
The mouse-mapping options enable you to assign viewer actions to mouse clicks and keyboard/mouse combinations. These options are available when running in stand-alone mode. To adjust or view the mouse mapping options, select Edit > Options, then Common > Viewer Setup > Mouse Mapping. For details, see Mouse Button Mapping.
