Parameters

inModel  Model
Model to be analyzed.
fromShapeInd  Int32
index of first natural vibration mode to be calculated. Numbering starts from one.
shapesNum  Int32
number of modes to be calculated.
maxIter  Int32
maximum number of vector iterations in the Mises procedure.
eps  Double
convergence criteria for determining the eigenvalues.
sign  Int32
sign of the eigenvalues: 1:positive only, -1:negative only, 0:never mind.
scaling  EigenShapesScalingType
type of scaling applied to the mode shapes.
eigenValues  ListDouble
Eigenvalues of the stiffness matrix.
outModel  Model
model with eigen-modes as load-case results.
