Tip: You can rename a created event by double-clicking on its names in the
bottom half of the Load Map dialog.
Create Time Series Events
Static subcases are
supported for all fatigue calculations with a Time Series loading type.
Click the Load Map tool.
Figure 1.
The Load Map dialog opens.
Using the bottom half of the dialog, specify how to create events then click
.
The fatigue subcases that are read from the result file can be paired with
load histories either manually or automatically.
All pairs will be
superimposed.
Note: The number of time points should be the same if the
pairs under the same event are superimposed.

Description
Manual Event Creation
Figure 2.
When Manual is selected and you click ,
an event is created without any load history and subcase pair
assigned. You can drag and drop an equal number of load histories
and subcases under an event.
Note: The subcases should be dropped
under an event first and then the load history
channels.
Auto Event Creation
Figure 3.
When Auto and Single
Event are selected, before you click ,
Select a subcase and a load history channel, or
Select multiple load histories and subcase pairs that have
an equal number of time points.
Only one event is created when you click .
Figure 4.
When Auto and Multiple
Events are selected, before you click ,
Select multiple load histories and subcase pairs.
The load
histories must have an equal number of time
points.
Total number of events created = Number of channels selected
/ Number of subcases selected.
Optional: Import an Event Mapper .csv.
Verify the Analysis type is set to Time
Data.
In the Event definition area, click
and select the event definition .csv file.
Both FE Subcases and load history files should be present in the loadmap. On
import of the Event Mapper .csv, FE subcases are
automatically paired with load history channels present in the Loadmap. The
CSV is organized by defining single or multiple Events
based on the IDs of FE loadcases and load history channels. Load histories of
the RPC/RSP format and multi-channel CSV are
supported.
Restriction: The load history files must be available
in the LoadMap context before importing an Event Mapper file.
Adjust the load magnitude, scale, offset, repeats, max gate range, and
configuration of the events/subcases.
Tip:
Apply the value of a parameter to all the events/subcases by
right-clicking on a value and selecting Apply value to
all events.
From the Subcase window, select any subcase increment.
Activate the checkboxes of the events to be considered in the evaluation.
