Hi all, Can we find all the eigen values and eigen vectors associated with a dynamic system using a SLEPcEigenSolver. If we can’t, can we find eigen values and eigen vectors from any range of modes or particular mode number. If so, what parameters do I need to change or add. [image (48)]

Hi, use eigensolver = SLEPcEigenSolver(K, M) eigensolver.parameters["problem_type"] = "gen_hermitian" eigensolver.parameters["spectral_transform"] = "shift-and-invert" eigensolver.parameters["spectrum"] = "target magnitude" eigensolver.parameters["spectral_shift"] = (2 * np.pi * 25) ** 2 to comp…

Sir,This the code through which I want calculate natural frequencies and mode shapes of all the modes associated with a dynamic system. from dolfin import * import numpy as np import json import matplotlib.pyplot as plt import scipy as sp %matplotlib inline mesh = Mesh() with XDMFFile("mesh/tetra.x…

Please see Read before posting: How do I get my question answered?

It’s difficult to help you debug without a MWE.
