Step 1: Launch ANSYS CFD-Post

Before you start CFD-Post, set the working directory. The procedure for setting the working directory and starting CFD-Post depends on whether you will launch CFD-Post standalone, from the ANSYS CFX Launcher, from ANSYS Workbench, or from ANSYS FLUENT:

• To run CFD-Post standalone, from the Start menu, right-click All Programs / ANSYS 12.0 / Fluid Dynamics / CFD-Post and select Properties. Type the path to your working directory in the Start in field and click OK, then click All Programs / ANSYS 12.0 / Fluid Dynamics / CFD-Post to launch CFD-Post.

• ANSYS CFX Launcher

  1.   Start the ANSYS CFX Launcher.

  You can run the ANSYS CFX Launcher in any of the following ways:

  • On Windows:
    • From the Start menu, go to All Programs / ANSYS 12.0 / Fluid Dynamics / CFX.

    • In a DOS window that has its path set up correctly to run ANSYS CFX, enter cfx5launch (otherwise, you will need to type the full pathname of the cfx command, which will be something similar to C:\Program Files\ANSYS Inc\v120\CFX\bin).

  • On UNIX, enter cfx5launch in a terminal window that has its path set up to run ANSYS CFX (the path will be something similar to
    /usr/ansys_inc/v120/CFX/bin).

  2.   Select the Working Directory (where you copied the sample files).

  3.   Click the CFD-Post 12.0 button.

• ANSYS Workbench

  1.   Start ANSYS Workbench.

  2.   From the menu bar, select File/Save As and save the project file to the directory that you want to be the working directory.

  3.   Open the Component Systems toolbox and double-click Results. A Results system opens in the Project Schematic.

  4.   Right click on the A2 Results cell and select Edit. CFD-Post opens.

• ANSYS FLUENT

  1.   Click the ANSYS FLUENT icon ( ) in the ANSYS program group to open FLUENT Launcher.

  FLUENT Launcher allows you to decide which version of ANSYS FLUENT you will use, based on your geometry and on your processing capabilities.

  

  2.   Ensure that the proper options are enabled.

  FLUENT Launcher retains settings from the previous session.

  (a)   Select 3D from the Dimension list.

  (b)   Select Serial from the Processing Options list.

  (c)   Make sure that the Display Mesh After Reading and Embed Graphics Windows options are enabled.

  (d)   Make sure that the Double-Precision option is disabled.

    You can also restore the default settings by clicking the Default button.

  3.   Set the working path to the directory created when you unzipped cfd-post-elbow.zip.

  (a)   Click Show More.

  (b)   Enter the path to your working directory for Working Directory by double-clicking the text box and typing.

  Alternatively, you can click the browse button ( ) next to the Working Directory text box and browse to the directory, using the Browse For Folder dialog box.

  

  4.   Click OK to launch FLUENT.

  

  5.   Select File/Read/Case & Data and choose the elbow1.cas.gz file.

  6.   Select File/Export to CFD-Post.

  7.   In the Select Quantities list that appears, highlight the following variables:

  • Static Pressure

  • Density

  • X Velocity

  • Y Velocity

  • Z Velocity

  • Static Temperature

  • Turbulent Kinetic Energy (k)

  8.   Click Write.

  CFD-Post starts with the tutorial file loaded.

  9.   In the ANSYS FLUENT application, select File / Read / Case & Data and choose the elbow3.cas.gz file.

  10.   On the Export to CFD-Post dialog, clear the Open CFD-Post option and click Write. Accept the default name and click OK to save the files.

  11.   Close ANSYS FLUENT.
