1. PURPOSE / DESCRIPTION

• To give an outline of steps (focused on Scheme codes) to run series of simulations and post-process them.
• Resources:
  • Fluent FAQs: http://goo.gl/Q4mLgv
    • Look under the section about Journal Files.
    • The questions themselves have links to forums regarding journal files as well.
  • ANSYS Customer Portal: https://support.ansys.com/AnsysCustomerPortal/en_us
  • User’s Manual within Fluent itself
  • Use Google to find various examples to change to fit various situations.

2. Scheme Tips

• A Scheme file (.scm) interacts with Fluent through the Text User Interface by inputting text lines formatted by the user. Using Notepad ++ or other editors to help with the code formatting is recommended.

• Best possible way to figure out Scheme is to try using the TUI commands to change settings, display graphics, save files, etc. and then copying the steps/inputs separated appropriately by spaces into the Scheme code. First try doing something basic in TUI of Fluent, and doing the same through Scheme.

• (Ti-menu-load-string(format #f ” INPUT TUI COMMAND ” variables))
  • ~a within the string acts as placeholder for variables
  • (Ti-menu-load-string(format #f “define/boundary-conditions/velocity-inlet inlet no no yes yes no ~a no 0 no no yes 5 10” Vmps))
    • Here ~a is replaced by a variable called Vmps that changes with each iteration of a loop
    • The string is what is “typed” into the TUI of Fluent, which means you can replicate it to check whether it works or not.
  • Spaces within the string are like pressing “Enter” in the Fluent TUI window

• Anything after a semicolon (;) is a comment.

• (Do ((i A (+ i B))) ((> i C)) . . . )
  • i = variable used to loop
  • A = beginning value
  • B = increment
  • C = upper limit (loop ends when value of i goes above 40)

• (define pi 3.14159265359)
  • pi = variable name
  • 14159265359

• (operation value value)
  • How to do basic mathematical operations
  • Need to look up the operators available
