Hi
I use Rec1980 for extract frequency from my eigenvalue analysis in abaqus, but there is a problem that i can't produce .fil file from my input file. I used :
*FILE FORMAT, ASCII
*MODAL FILE, FREQ=1
*FREQUENCY
10
in my input file but no .fil file was generated. My question is how can i produce .fil file from my input file?
(I used your Gui version and in that one also there is not eigenfrequency option in variables.)
thank you
Could you send me a version of your input file in order to fix the issue?
Best
