Hi~ I have a problem wiht swich whitch is located in STAR GUIde. It is need to turn the switch on to use Subroutine?? What is mean each Star GUIde' switches?

The switches are kind of 'beta-features' that turn on different things that are not yet fully implemented in Star-CD. You normally don't need them to use subroutines, I think there is only one exception when you want to use a subroutine for a turbulence model. For all the other subroutines you have to choose "user" out of the possible choices and write the necessary code via "user-subroutines" in the Star menu to the subdirectory "./ufile".

Thanks for your help. If I want to use varcmu.f, do I need to turn switch on? or don't need to turn on?

Hi there,

no, I think you need a switch for subroutine "sor???"; I think yours should work.

Thank you for your help!! Have a nice day.^^
