- Create the model and assign support conditions.
- Select Define > Functions > Time History to define a time-history function which characterizes load variation over time.
- Assign load conditions to the model.
- Define either a modal or direct-integration time-history load case through Define > Load Cases.
- Enter on the Load Case Data form under Loads Applied, the following fields:
- Load Type. Select load pattern or specify an acceleration.
- Load Name. Either load pattern name or acceleration direction
- Function. Select the time history function which characterizes load variation in time.
- Scale Factor If acceleration load type apply scale factor as a percentage of G in current unitunits
6. On the left side of the time history load case dialogue under Properties, users will find options to specify load sequencing using the 'Continue from End state of' field, an option to select a mass source, and option to specify P-delta if it's a nonlinear direct integration time history case.
