Define modal analysis cards, such as extraction methods, frequency range, modes to
expand, iterative solver tolerance, modes significance level and solution control
options.
From the menu bar, click Tools > Analysis Setup.
In the Analysis Options dialog, set the modal analysis in
the model.
All commonly used cards and options for modal analysis in the ANSYS solver are listed in the dialog. You do not
need to search for relevant cards in the control card list, and you do not
need to know the control cards that are used for modal analysis. All other
implied ANSYS cards, such as /SOLU, SOLVE are
set up automatically. If any option or card is not required, then default
values will be exported. For example, in the image shown below, if Mass and
stiffness matrix multiplier value need not required.
If modal analysis needs to be carried out in the ANSYS solver, this dialog needs to be set up before
exporting the model to an ANSYS deck.
