EigenValueGuess (Numerics)

EigenValueGuess (Numerics)#

Defines the target eigenvalues used by FELiCS in modal analyses.

Type
list of floats or complex values
Default
[]

Example#

"Numerics": {
    "EigenValueGuess": ["0.1+1.2j", "0.1-1.2j"]
}

Real eigenvalue targets may also be provided:

"Numerics": {
    "EigenValueGuess": [0.0, 1.0]
}

Complex eigenvalues should be provided as strings.

Real and complex targets may also be combined:

"Numerics": {
    "EigenValueGuess": [0.0, "0.1+1.2j"]
}

Each entry defines one eigenvalue target used internally by the eigensolver. This parameter is then passed to the setTarget() method of the SLEPc eigenvalue solver.

This parameter is only relevant when Case.AnalysisMode is set to Modal.
