Abaqus performs the calculations just fine, but I need eigenvalues and (mass scaled) eigenvectors to perform some other calculations.
I am doing this because I could not find an efficient way to export eigenvalues and eigenvectors in a readily digestible format. Thus, the question.
Thank you...
Greetings,
I am working with large Abaqus model and I need to extract its eigenquantities and import them into MATLAB.
Is there an efficient way to do this?
So far I have extracted the Mass and Stiffness matrices (keywords *MATRIX GENERATE and *MATRIX OUTPUT), imported them into MATLAB (via...
with swept sine excitation the response may be corrupted by transients.
The stepped sine excitation is more conservative in this sense - I could stitch together several sinewaves to create a discrete-swept-sine excitation though.
My problem is that either way it would take just too long to...
Hello,
I have a structure with a lap joint which I tested at different forces and found being nonlinear (stepped sine excitation revealed softening behaviour in the FRF).
Now I would like to be able to predict the forced response of my FEmodel** by extracting the very same FRF I extracted via...
