! Purpose:
! -------

!> \file cs_user_parameters-rotation.f90
!>
!> \brief Rotation parameters example.
!>
!>  See \ref f_parameters for examples.
!>
!>   If the Code_Saturne GUI is used, this file is not required (but may be
!>   used to override parameters entered through the GUI, and to set
!>   parameters not accessible through the GUI).
!>
!>   Several routines are present in the file, each destined to defined
!>   specific parameters.
!>
!>   To modify the default value of parameters which do not appear in the
!>   examples provided, code should be placed as follows:
!>   - usipsu   for numerical and physical options
!>   - usipes   for input-output related options
!>
!>   As a convention, "specific physics" defers to the following modules only:
!>   pulverized coal, gas combustion, electric arcs.
!>
!>   In addition, specific routines are provided for the definition of some
!>   "specific physics" options.
!>   These routines are described at the end of this file and will be activated
!>   when the corresponding option is selected in the usppmo routine.
