CFX-Solver Manager BasicsCFX-Solver Manager is a graphical user interface that allows you to set attributes for your CFD calculation, controlthe CFX-Solver interactively, and view information about the emerging solution. As an alternative to using theCFX-Solver Manager interface, you can also operate CFX-Solver from the command line, which is particularlyuseful for batch mode operations (see Chapter 11, Starting the CFX-Solver from the Command Line (p. 111)).This chapter describes:•Starting CFX-Solver Manager (p. 1)•Working with the CFX-Solver Manager Interface (p. 1)•Customizing CFX-Solver Manager (p. 5)Starting CFX-Solver ManagerYou can start CFX-Solver Manager in different ways:•Using ANSYS Workbench. For details, see ANSYS CFX in ANSYS Workbench (p. 51) in the ANSYS CFXIntroduction.•Using the CFX-Launcher. For details, see Using the ANSYS CFX Launcher (p. 49) in the ANSYS CFXIntroduction.•If CFX-Pre is launched and a simulation is open, you can launch CFX-Solver Manager by writing a solver file.For details, see Write Solver Input File Command (p. 48) in the ANSYS CFX-Pre User's Guide.Working with the CFX-Solver Manager InterfaceCFX-Solver Manager is an interface that displays a variety of results as outlined below. It is generally used to viewthe plotted data during problem solving.Figure 1.1. CFX-Solver Manager Interface1Release 12.1 - © 2009 ANSYS, Inc. All rights reserved.Contains proprietary and confidential information of ANSYS, Inc. and its subsidiaries and affiliates. By default, the convergence history plots appear to the left or the top. The text output window appears to the rightor the bottom. There is an adjustable split between the windows that is oriented either horizontally or vertically,depending on the aspect ratio of the entire CFX-Solver Manager window (also adjustable).The following parts of the interface are described next:•Workspace Selector (p. 2)•Convergence History Plots (p. 2)•Text Output Window (p. 3)•Multi-Configuration Run History Page (p. 4)Workspace SelectorThe Workspace selector is a drop-down list that shows the current run name and enables you to switch betweenruns.1.Click the arrow of the Workspace drop-down list.2.Select the run you want to view.Convergence History PlotsConvergence history plots are shown on monitor tabs. Each monitor tab shows at least one plot of a variable versustime step, where the variable can be an RMS or maximum residual, or a user-defined variable. For example, theMomentum and Mass monitor tab shows plots of the RMS/maximum residuals for pressure and the U, V, and Wcomponents of momentum. A legend appears below each plot to show the variable associated with each plot line.You can:•Configure/edit a monitor from the Monitor Properties (p. 95) dialog box. To invoke that dialog box, you cando one of the following:•Right-click in the plot area of the monitor tab and select Monitor Properties from the shortcut menu.•Select Workspace > Workspace Properties from the main menu, then select a monitor from the WorkspaceProperties dialog box and click Edit.•Click any of the plot lines to view the value at the nearest time step.•Toggle between showing RMS or maximum values by right-clicking in the monitor tab and selecting SwitchResidual Mode from the shortcut menu.•Hide or show any monitor tab from the Monitors Menu (p. 109). Another way to hide a monitor tab (other thanthe Out File monitor tab) is to right-click in the monitor tab and select Hide Monitor from the shortcut menu.•Delete a monitor tab by right-clicking in the monitor tab and selecting Delete Monitor from the shortcut menu.Other actions that can be performed using the shortcut menu on the monitor tab are described in the followingsections:•Printing an Image of the Convergence History (p. 2)•Saving a Picture of the Convergence History (p. 3)•Exporting Plot Data (p. 3)•Exporting Monitor Data from the Command Line (p. 3)Printing an Image of the Convergence HistoryYou can print a picture of the convergence history plot:1.Right-click in the convergence history plot and select Print.The Print dialog box appears.2.Configure the printer as required.3.Click Print.Release 12.1 - © 2009 ANSYS, Inc. All rights reserved.2Contains proprietary and confidential information of ANSYS, Inc. and its subsidiaries and affiliates.Workspace Selector Saving a Picture of the Convergence HistoryYou can save a picture of the convergence history plot:1.Right-click in the convergence history plot and select Save Picture.The Image File dialog box appears.2.In the Image File dialog box, select a location to which to export the image.3.Under File name, enter the name for the file.4.Under File type, select the format to export.5.Click Save.Exporting Plot DataData from any plot monitor can be exported. The data format for the exported file consists of comma-delimitedentries. This data can be used as the basis for import to another application.1.Right-click in the convergence history plot and select Export Plot Data.The Export dialog box appears.2.Select a location to which to export the data.3.Under File name, enter the name for the file.4.Under File Type, select the format to export.Files are saved with a . csv extension by default, but this can be modified as required.5.Click Save.Note that monitor data can also be exported using the command-line application cfx5mondata.Exporting Monitor Data from the Command LineThe cfx5mondata application provides a command-line driven mechanism to query or extract monitor data fromthe directory in which a solver run is executing, a CFX-Solver Results file, or a monitor file. When extracted,monitor data are written in a comma-separated format that is similar to the output generated by the Exporting PlotData capability.To obtain a complete list of available command line options for cfx5mondata type the following command intoa UNIX terminal or a suitable Windows command line and press Return or Ente...
