안녕하세요

현재 주파수 응답을 보는 중, 허수부에 대한 응답이 출력되지 않아 문의드립니다.

Punch 파일에서는 허수부 응답이 출력되지 않는건가요?
(Complex, Real, Imag 모두 확인해보았으나 결과는 동일하였습니다)

Hi,

I will reply in english, I hope this is fine for you.
In OptiStruct, if you resquest ACCELERATION(PUNCH) = ALL, the punch file will write for each frequency and each grid, 4 lines: the third and forth lines correspond to the imaginary portion.

This page on OptiStruct Help details more about this: https://2024.help.altair.com/2024.1/hwsolvers/os/topics/solvers/os/punch_files_r.htm?zoom_highlight=punch+file

Thanks to you, I understand the format of the .pch file.
Thanks.

But I still have a question.
Of course, if I don't set the attenuation separately, is it right that the imaginary part is displayed as 0?

If I didn't set the attenuation coefficient G separately!
