Hi to all,
I am doing a 2D axisymmetric simulation in Fluent.

1)My BC's are simple cylinder which has rotating outer wall @ 3600 rpm and innerwall is fixed.Fluid is entering and leaving axially.

2)Now i have to calculate Moment on rotating wall.While i report
force -->Moment -->Moment on axis (-1 0 0) i am getting two values (23.23 & 37.94) from fluent report.

Moments- Moment center (1 0 0) Moment Axis (-1 0 0)
Moments (N-m) Coefficients
Pressure, Viscous, Total, Pressure, Viscous, Total,
0, 23.23 , 23.23 , 0 , 37.94, 37.94
-------------------------------------------------------------------------
Net 0, 23.23, 23.23, 0, 37.94, 37.94

I could n't able to understand why two values.

could anybody explain me.Thanks in advance
