ANSYS FLUENT TUI

Over the different versions, while new features have been added, the names of some of commands have been altered and many have been removed / consolidated. For example, 'grid' has been replaced with 'mesh', display set colors background white" has been replaced by "display set colors graphics-theme-color white". In version 2020 onwards, "define b-c material" has been shortened to "define material". The code presented here is valid up to version 2016.

License Manager: LMTOOLS

Most of the CFD programs be it ANSYS FLUENT or STAR-CCM+ use LMTools to manage the licenses at their customers. The executable utility is installed in the same folder where main program such as ANSYS FLUENT is installed. The syntax to use LMSTAT is: lmstat [-a] [-c license_file_list] [-f [feature]] [-i [feature]] [-s[server]] [-S [vendor]] [-t timeout_value]. The purpose of each option is:
  • -a: Displays all information
  • -c license_files: Uses the specified license files
  • -f [feature]: Displays 'users' of feature. If feature is not specified, all features are displayed
  • -i [feature]: Displays information from the feature definition line for the specified feature, or all features if feature is not specified
  • -s [server]: Displays status of all license files listed in $VENDOR_LICENSE_FILE or $LM_LICENSE_FILE on server, or on all servers if server is not specified
  • -S [vendor]: Lists all users of vendor’s features
  • -t timeout_value: Sets connection timeout to timeout_value which limits the amount of time 'lmstat' spends attempting to connect to server.
On Windows machines, you can use: "<Installation-Folder>\lmstat.exe" -s licServer -i licFeature > licStatus.txt to print the output to a file. To know what are the name of features available in license file, use -a option, that is: "<Installation-Folder>\lmstat.exe" -s licServers -a > licStatus.txt. Alternatively, you can copy the lmutil.exe file from installation folder to any other local folder and use the command: c:/Users> lmutil.exe lmstat -s licServers -a. lmutil.exe is an independent executable supplied with different commercial tools such as ANSYS, ANSA, STAR-CCM+ and lmutil.exe supplied with STAR can be used to fetch licenses for ANSYS by supplying appropriate server names.

Finding Names of Feature: to use -f option, one need to know the exact names of feasures. This can be found in license.dat file or check the output from -a options. lmutil.exe lmstat -s licServers -f "feature_name"
