Large rotations (parabolic extrapolation)

In this scenario, you have to use parabolic extrapolation. There are two ways to do this job; either you could use the graphical interface in the step module (Figure 1) or use the “*STEP, EXTRAPOLATION=PARABOLIC” command in the input file. To use this command, go to the “Edit Keywords” window, write the command, and click the OK button (see Figure 2).
