Hi everyone,
I am working on vibration analysis of rotating shaft.

When I use "Orbital Plot" in Rotordynamic Tools, I can see only 2 degree of motion. 

So, I use the APDL code below but I cannot get any orbit plot.

esel,s,ename,,188                 ! Select BEAM188 elements to produce orbits
set, 2, 5                                  ! Visualize orbits for test point 2, modal 5
/view,,0.5,1,0.5                       ! Change view (x,y,z)
/ANGLE, , 45, YS, 1               ! Rotate view (around Y)

/show, png,                             ! Set white background
/pnum, elem, 0                   
/replot                            

/rgb, index, 100, 100, 100, 0  ! Set white background
/rgb, index, 0, 0, 0, 15          

plorb                                       ! CREATE ORBIT PLOT

 

I want to display an orbit plot showing the rotation of the shaft as shown in the image below.

Can anyone tell me where I'm going wrong?
