WebPerforming a frequency analysis means solving the following eigenvalue problem (see Eigenvalue extraction ): (KNM −λM NM)ϕN =0, (1) (1) ( K N M - λ M N M) ϕ N = 0, where λ λ represents the eigenvalues, ϕN ϕ N represents the eigenvectors, and M NM M N M is the mass matrix. In addition, the eigenvectors are scaled such that either. WebEnsure inheritance path. It is important to ensure that the variations defined by the uncertainty and sensitivity analysis Design Variables will have the intended effect. Uncertainty and sensitivity analysis works by applying variations to a copy of the base model and these changes are applied to the object defined in the Variable.
