  Dear all,
  
  I´m trying to run a simulation in Fluent 19.2 with TUI commands. Some of the features are: 3ddp, 6DOF, Dynamic-mesh, parallel in 8 cores. Do you know how can I enable the "iterate" command from the "solve" menu?
  
  I keep getting the message below when asking for the available sub-menus.
  
  """"""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""
  
  /solve> help
  
  Type "?" for help on a specific command.
  
  Type "?" to enter help mode, and "q" to exit help mode.
  
  The commands below are available in this menu.
  
  Those followed by "*" are currently disabled.
  
  animate/ monitors/
  
  cell-register-operations/* multistage-time-iterate*
  
  cell-registers/ patch
  
  convergence-conditions/ report-definitions/
  
  dpm-update* report-files/
  
  dual-time-iterate* report-plots/
  
  execute-commands/ set/
  
  initialize/ update-physical-time*
  
  iterate*
  
  mesh-motion
  
  """""""""""""""""""""""""""""""""""""""""""""""""""""""
  
  Thanks for your help,

  Is it transient? I guess so because of 6dof. The command will be dual tine iterate. Just press enter whenever you are under solve and all commands are listed. If you are using a new version just use the search field to lookup the commands.

  I think Frank's answered here too https://forum.ansys.com/forums/topic/non-existing-commands-and-how-to-start-a-simulation-without-gui/ please don't multi-post. Amine's correct, you'll need to use the dual-time option and I'd advise setting everything up using the GUI before launching in batch.
  
  The missing graphics options may be linked, but could also be caused if you launch Fluent without graphics.

  Thank you for your responses.
  
  I deleted the other thread. Sorry for multi-posting.
  
  I'm using transient formulation with "unsteady-1st-order" model. Fluent can't recognize the "dual-time-iterate" command neither.
  I'm launching fluent in batch mode with both "-g" and "-gu" commands both to check if the graphics may be linked but still doesn't work.

  Are you using the Automatic Case Modification Feature? Add all details of the run.

  Yes, I was using it.
  
  Once I unselected the "Automatic Case Modification" option the "Dual-time-itarate" command became available. Now I'm able to run the simulation with TUI.
  
  Thank you very much for your help!
  
  Kind regards,
  
  Jorge
