Hi all,
i am doing buckling analysis in Abaqus. While crearting a new step, i dont have clear idea about the terms below
No of eigenvalues requeted:
Maximum eigenvalue of interest:
Vectors used per iteration:
Maximum no of iterations:
I want suggestion from you.
Thank You in advance

eigen values in abqus
No. of eigen values: The number of buckling modes that you want the system to calculate (say, NE)
Maximum eigenvalue of interest: The number of eigen values of interest (NI <= NE), This is helpful, when the system could not find NE number of eigen values (could not converge) but, could show you NI, then you will be able to see NI modes in the results.
Maximum no of iterations:The number iterations that you allow the system to take to calculate NE. some times, if number of iterations are small, then the system may not converge. In that case, increasing this number might give you a converged solution
