Hi everyone,

I am trying to solve spinning cylinder problem for compressible flows.
So I added GRID MOVEMENT option to config file.
My option about movement is here.

GRID_MOVEMENT= YES
GRID_MOVEMENT_KIND= MOVING_WALL
MACH_MOTION=0.8

MARKER_MOVING=(Body)
MOTION_ORIGIN_X=0.0,0.0
MOTION_ORIGIN_Y=0.0,0.0
MOTION_ORIGIN_Z=0.0,0.0

ROTATION_RATE_X=8572.032
ROTATION_RATE_Y=0.0
ROTATION_RATE_Z=0.0

But the following result is returned.

185 ------------------------------ Begin Solver -----------------------------
186
187 Setting the moving wall velocities.
188 Storing grid velocity for marker: Body.
189 Translational velocity: (0, 0, 0) m/s.
190 Angular velocity: (29.805, 0, 0) rad/s about origin: (0, 0, 0).

Why are diffrent rotation rate of option file(8572.032) and results file(29.805)?
