Modal Reduced-Order Model
The
Modal Reduced-Order Model
(
) study step is used for exporting reduced-order model matrices.
You can add a Modal Reduced-Order Model study step for exporting the reduced order model matrices after an Eigenfrequency study step for computing the eigenfrequencies and eigenmodes of a linear or linearized model in the frequency domain.
A Modal Reduced-Order Model study step uses the
Modal Solver
. It uses the transient equation form for the export. The matrices can be accessed through the COMSOL Multiphysics API or in table format from a
System Matrix
derived value.
The
Modal Reduced-Order Model
is a legacy feature. You are advised to use the
Frequency Domain, Modal Reduced-Order Model
or
Time Dependent, Modal Reduced-Order Model
studies to obtaine matrices for reduced models.
