Load Maps

Use the Load Map tool to import/create multiple channels (load histories) which are then paired with subcases/loadsteps to create the fatigue events.

Figure 1.
The Load Map dialog consists of three parts. The top-left part is used to create, import, and manage the channels (load histories); the top-right part displays the available subcases; and the bottom part is used to create events.
Tip: Right-click in empty space in the channel or event windows to quickly expand or collapse folders.

The information displayed in this dialog is dynamic. The available options change depending on the load type and the channel type.

The following table summarizes the channel types that are available based of the type of loading assigned in the fatigue tools.

Note: Derived loadcases (by linear superposition) can now be created and saved in HyperLife session files.
