Solution Step/Subcase dialog box (Nastran Real Eigenvalues)

Solution
Name Sets the name of the subcase.
Solver Type Displays the solver for the solution, as Simcenter Nastran.
Analysis Type Displays the analysis type, such as Structural.
Solution Displays the solution type, as SOL 103 Real Eigenvalues.
Step Specifies the type of subcase to create.Available subcases are:Subcase - Normal ModesComputes the normal modes and natural frequencies.Subcase - Normal Modes, Residual Vector LoadsComputes the normal modes and natural frequencies using the residual vector loads method to include loads and enforced motion.Subcase - StaticsSelects the static subcase to be applied to the modal solution. The static subcase is used to form the differential stiffness, created by pre-loading or pre-stressing.
Create Step Creates the new step as a subcase in the SOL 103 Real Eigenvalues solution.
