Inputs

NameIDDescriptionType
ModelModelModel for which to calculate natural vibrationsModel
From indexFromIndIndex of first natural vibration mode to be calculated. Numbering starts from one.Integer
Number of modesNModesNumber of modes to be calculatedInteger
Maximum number of iterationsMaxIterMaximum number of Mises vector iterations for determining the eigenvalues.Integer
EpsilonEpsConvergence criteria for calculating the natural vibration frequencies.Number

Outputs
