Dear Users,


Actually I am trying to do some analysis of a moving bus. I want to define the doors as WALL boundary condition for some time (iterations) and then to OPENING or OUTLET boundary condition and again to WALL (as opening and closing doors) for some flow time.

Could anyone help me how can I define the UDF for this type of problem.

regards

Hi,
you can do that with a simple journal file. I didn't see a UDF for that before!

First of all thanks for the reply. I have no idea about creating journal file, do you know where can I find any material or any kind of tutorial regarding this (creation of journal file).

thanks

refer to FLUENT user guide,<creating and reading journal files>.
you can automate FLUENT commands with journal files and they can be contained of TUI commands.
e.g: set a specific B.C. up to iteration (100) and then change to another...
