cycphase

[james80]

I am doing a cyclic symmetry modal analysis. I use cycphase to obtain the max disp at a node#10057. I observe that it is not returning the correct value.

Cycphase is returning Usum max at 0 phase angle while at 120 phase angle Usum is the max
Please help me understand this problem
thanks

> Cycphase is returning Usum max at 0 phase angle while at 120 phase angle Usum is the max

From the list you've produced it appears that the Usum max is at 120 degrees.

Yes, Usum is max at 120 degrees, but when i do a cycphase,list, ansys gives me
0 -76.92 15.58 106.30 132.1337541
as the max displacement instead of
120 146.73 -29.73 -202.89 252.1503763

I dont know why?
