Specialist Durability > Specialist durability load events
Automatically creating a duty cycle load event
Use the Auto Duty Cycle command to automatically create different superposition load events and combine them to generate a single duty cycle load event by defining:
The CSV file that contains a list of superposition load event names, and their corresponding load history file name and number of repititions. Optionally, the file can also specify the duration and distance of each superposition load event.
The folder that contains the load history files.
A superposition load event template that already exists in the Simulation file. The template must contain a single load history file, finite element results from one or more source files, and matching results. You can define additional settings for the template, which are applied to the subsequent superposition load events.
