The sawtooth time history function is a periodic function. A single cycle of a sawtooth function is defined by seven points (time, function value). Those seven points, in order, are (0, 0), (Ramp time, Amplitude), (0.5 * Period Ramp time, Amplitude), (0.5 * Period, 0), (0.5 * Period + Ramp time, Amplitude), (Period Ramp time, Amplitude) and (Period, 0).

The following parameters are specified in the sawtooth time history function template.

Period edit box. Use the default or specify the time in seconds that it takes for the sawtooth function to complete one cycle.
Ramp Time edit box. Use the default or specify the time that it takes for the sawtooth function to ramp up from a function value of 0 to its maximum amplitude.
