TASC5.0 does not vibrate, while ASPEN TASC 2006 vibrates constantly. What is the reason? ?

The heat exchanger I calculated using TASC5.0 showed no vibration, but when I ran the calculation again with ASPEN TASC 2006, vibration was detected every time. What should I do if I change it? Ignore the vibration? But it’s really troublesome to solve the vibration problem.
If you’re not confident about this, you can actually refer to the examples related to vibration in the appendix of GB151 and carry out the calculations by yourself; if the results are satisfactory, then there’s no need to worry. As for any discrepancies in the results obtained using software, it might be due to the different parameters chosen by each software in performing vibration calculations. This is just my personal opinion, for reference only, hehe
The calculation for 6.0 should represent an further refinement of the heat exchanger parameters based on 5.0 to account for actual conditions, but generally the change will not be significant.
Doing a manual check, the deviation for GB151 is around 5%.
