Comments, Questions, and Answers:
Item #1:
We are analyzing harmonic load with known Frequencies and Forces. Is there a way we can convert frequency domain to time domain in order to apply time history load?
Answer:
I apologize for the inconvenience, however AutoPIPE (v.09.06.xx.xx and lower) does not have this ability at this time.
Item #2: Why we see no displacement at the node where an AutoPIPE Harmonic load is imposed in the same direction?
Item #3:
Where would a user get the *.HMF file required by AutoPIPE?
Answer:
The HMF file can be generated by the following sources:
a. Bentley PULS can automatically generate this file
b. Other vibration analysis software.
c. Manually by the User, defined from a vibration recording or other source (see AutoPIPE help for details).
Item #4:
Where in API 618 does it say to reduce allowable stress by 2?
Answer:
The divide by 2 is because of peak to peak nature of the harmonic input. The maximum stress is half the stress range peak to peak.
