Defining time step intervals for transient or nonlinear analyses

Create a Time Step modeling object to define the number of time step intervals at which the software should generate a solution. You can use a Time Step modeling object when you are performing a Nastran transient analysis (SOL 109 or SOL 112) or a Simcenter Nastran Advanced Nonlinear analysis ( SOL 601, or SOL 701). When you solve or export your model, the options on the Time Step dialog box define a TSTEP bulk entry in your Nastran input file.
