Answer

  1. To start, all the loading hypotheses must be defined in the model, for example, Self Weight, Dead Loads, Live Loads, Snow Loads, etc.

  3. In the properties list of the Modal Analysis Hypothesis you must define the following parameters:

  4. a. Modes - Number - the number of eigen modes defined by the user corresponding to the structure type.

    b. Masses - Definition - select "masses obtained by combining static loads". This option allows you to define the component of modal mass.

    c. Masses - Combinations - you can define the coefficient which is combined with the load cases in the modal mass.


  5. One the finite element analysis is done, you can view the structure's eigen modes.
