Run Fluent Interactively


  • Running Fluent interactively is similiar to the usual workflow for an interactive program on the cluster. The workflow includes
    • Setup VNC environment
    • load Ansys in environment
    • Launch Fluent
    • Set number of processors
  • When the gui launches, you MUST set the number of processes to the number of cpus requested


Set up Interactive (VNC) Session

  • Please see the VNC guide for instructions on how to set up the Interactive VNC session

Start Fluent on VNC

  • Open terminal in the vnc window by clicking top left Applications > System Tools > scroll down to terminal
  • all commands here on will be typed in terminal in VNC
  • To use fluent, we must have Ansys loaded
  • Commands to list available versions, load Ansys, and run:
module avail ansys #lists available versions
module load ansys/17.0 #loads Ansys 17.0
fluent  #runs fluent


Setting CPU Number

  • Once you run the command fluent, a gui should pop which allows you to adjust parameters
  • Make sure you set num processes number to the number of cpus you requested when submitting the interactive job
