Create a modeling object
Use this procedure to a create modeling object for your solution or solution subcase. Modeling objects contain various settings that determine how the solver processes your model.
Choose Home→Properties→Modeling Objects .
In the Modeling Objects Manager dialog box, from the Type list, select the modeling object you want to create for your solution.The Type list displays modeling objects that are specific to the solver. Some modeling objects, such as Bulk Data Echo Request, Complex Eigenvalue, and so on, appear as options for several solvers and solution types. Other modeling objects, such as Aerodynamic Divergence Data, Forcing Frequencies, and so on, appear as options for only a few specific solvers and solution types.
Click Create.A dialog box for the modeling object you are creating opens.
Complete the options in the modeling object dialog box.
Click OK.In the Modeling Objects Manager dialog box, the new modeling object appears in the Selection list in the Selection group. You can edit, copy, and delete modeling objects from this list.
Repeat steps Create a modeling object–Create a modeling object to create additional modeling objects.
Click Close.
