Are there any examples showing the Coriolis effect in a harmonic response analysis?
Yes, please see the ANSYS 8.0 example below. A full harmonic response analysis
with PIPE16 elements is provided. Only a few ANSYS elements have this "SPIN"
capability, including PIPE16. There are license restrictions for this ability, as well.
