CastemModalAnalysis

class compas_fea2_castem.problem.CastemModalAnalysis(**kwargs)

Bases: ModalAnalysis

Castem implementation of Modal Analysis step.

The VIBR method is used for the resolution of (K-(2*PI*f)^2M).u = 0. https://www-cast3m.cea.fr/index.php?page=notices&notice=VIBR

The rigidity and mass matrix are generated with the RIGI et MASS operators.

The ‘INTERVALLE’ method of resolution of the VIBR operator is implemented. The other methods are not implemented yet.

Perform a modal analysis of the Model from the resulting state after an analysis Step.

Parameters:

modesint

Number of modes.
