      Good day


      I tried to serch on ansys's giude, or a video, to define a Macros that include a change of under relaxation paraleters during calculation.


      Is it possible to define a command in fluent to change under-relaxation-factors during calculation?


      Thanks for the help

      Probably, you'll want the solution steering tools (case modification) and need to find the command syntax in the text user interface (TUI). It's easy enough once you're familiar with it, will bring up the menu & q (Q) takes you up a level.

      Do you want to change some controls after some iterations?


      Please check calculation activities - execute command. 


      you can find more information in help document.

      Good day and thank for the help


      I tried to define a new Macro and after clicking the botton i tried to define a new Under Relaxation Factors using "/define" and search in the list for URFs but i wasn't able to find them.


      I think that the correct process is "DefineMacros", then define it on the Command window so define the new parameters and "EndMacros", is ti right?


      Regards.

      Yes and no. The GUI macros aren't as reliable as the TUI.  The UR factors are probably in /solve somewhere, I'll leave you to hunt for the menu. Or try the search tool at the top!
