class elastodynamicsx.solutions.ModalBasis(wn: ndarray, un: List[Vec], **kwargs)[source]

Bases: object

Representation of a modal basis, consisting of a set of eigen angular frequencies \(\omega_n\) and modeshapes \(\mathbf{u}_n\).

At the moment: is merely a storage + plotter class In the future: should be able to perform calculations with source terms, such as modal participation factors, modal summations, …

Parameters:

wn – eigen angular frequencies
un – eigen modeshapes

property fn: ndarray: The eigen frequencies \(f_n = \omega_n/2\pi\)

property wn: ndarray: The eigen angular frequencies \(\omega_n\)

property un: List[Vec]: The eigen modeshapes \(\mathbf{u}_n\)

plot(function_space: FunctionSpace, which='all', **kwargs) → None[source]

Plots the desired modeshapes

Parameters:

function_space – The underlying function space
which – ‘all’, or an integer, or a list of integers, or a slice object
kwargs – shape: (default: attempts a square mosaic) shape of the pyvista.Plotter factor: (default=1) Scale factor for the deformation wireframe: (default=False) Plot the wireframe of the undeformed mesh

Example

plot(V)                   # plots all computed eigenmodes
plot(V, 3)                # plots mode number 4
plot(V, [3,5])            # plots modes number 4 and 6
plot(V, slice(0,None,2))  # plots even modes
