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
You can specify the option:
*NODE FILE
U
instead of the option:
*MODAL FILE, FREQ=1
thanks for your answer, but i want to extract natural frequency. if i don't use those keyword, .fil file doesn't produce and when i use them .fil file generated but my data (eigenfrequency of model) are not extracted.
Is there any other method for export eigenvalues of model using matlab except Rec1980?
Hello,
You should specify at least one results file output variable identifier at the data line of the *MODAL FILE option. The available identifiers are the following:
GU,GUn,GV,GVn,GA,GAn,GPU,GPUn,GPV,GPVn,GPA,GPAn,SNE,SNEn,KE,KEn,T,Tn,BM
Best regards,
