Eigenfrequency
The Eigenfrequency study step is used to compute eigenmodes and eigenfrequencies of a linear or linearized model.
Syntax
model.study(stdname).create(fname, "Eigenfrequency");
model.study(stdname).feature(fname).set(pname,value);
Description
Study step.
The following properties are available.
on | off
manual | region | all
Eigenvalue search method; the all method finds all eigenvalues for a full matrix and can only be used for small eigenfrequency problems.
lm | lr | sr | li | si
init | sol
Method used for linearization point, which for sol is determined by the current solution (that is, the solution computed by the previous feature in the sequence).
zero | solution object
all | auto | first | last | from_list | interp | manual | solution number
on | off
on | off
on | off
init | sol
auto | all | first | last | from_list | interp | manual | positive integer
Reference to study or "zero" for zero solution.
