EigenValue Calculation
The eigenvalue calculations could be performed during a dynamic simulation using the commands:
EigenVal Time 1.0 ! Perform eigenval calculation at time=1.0sec
EigenVal NumberOf 20 ! Try to compute 20 vercotrs
EigenVal Algorithm Lanczos ! use Lanczos algorithm
EigenVal ModeScal 2 ! Scale modes with factor 2 for easier visualization
The EigenVal command is extended from version 8-5.
Usfos input files to the actual example are found in the following two files:
=> Usfos Control File
=> Model File
