i've already solved this problem, but now i've a new one, i'm trying to get eigen values with frequencies an period and it gives a error, it says: ArpackSolver::Error with _saupd info = -9999 Could not build an Arnoldi factorization.IPARAM(5) the size of the current Arnoldi factorization: is 12facto...

I'm having a huge problem, i made a 3D model file, but it's gaving me very strange values to reaction when i look i didn't see anything strange i can't identify any error i'll put my file above # Units: kN, m, sec # # wipe; # clear opensees model model basic -ndm 3 -ndf 6; # 3 dimensions, 6 dof per ...
