How to change the relax factor?
 
Hello every one! Is there any button in CFX-setup to change the relax factor of iteration computation? How can I change it? By add some command line in command file or add a fortran file?

CFX what? Tascflow? CFX-5.5, CFX-4.4?

I mean the relax factor in the process of iterate calculate by the solver

I understand, but for which CFX-package? CFX4.4, CFX5.5, CFX5.4.1, CFX4.1, CFX-Tascflow???

There is definitely a menu called 'Underrelaxation factors' in which you can relax equations separately. Check ths solver manual. The solver manual also gives a nice example on relaxation using the Fortran Subroutine USRCVG. So, the choice is yours. These should bring you further.
