[ABAQUS] Huge number of natural frequencies issue (70eigenmodes/2Hz ca.). Any hints?
[ABAQUS] Huge number of natural frequencies issue (70eigenmodes/2Hz ca.). Any hints?
(OP)
Hi everyone.
I'm performing a natural frequency extraction of a railway, in order to get its eigenmodes in the range 0-1200Hz.
However, while performing the Frequency step needed for the frequency extraction, ABAQUS computes an enormous amount of natural frequencies, ca. 70 for a 2Hz frequency range.
Anybody could give me some hints about how to overcome this issue and get an acceptable frequency analysis?
Regards,
Omar
