recorder EnvelopeNode how does it work?

Post by buffs » Tue Jan 21, 2020 1:50 am

I tried to run the code at page 11 of this content: https://opensees.berkeley.edu/workshop/ ... cKenna.pdf
to calculate the spectrum from acceleration timeseries of mine.
After some small changes to code (not working actually) I am stuck with recorder EnvelopeNode giving an empty file... while recorder node gives properly the displacements. Did anyone succeed calculating spectra?
Thanks a lot.

I noticed a strange behaviour, the file expected is not 'visible' (regardless the OS, same behaviour in Win and Linux) as soon as you don't work on another file, therefore I want to add a 'fake' recorder at the end just to make the former visible...

It should work properly. Could you follow the syntax here:
