Frequently Asked Questions
This section provides quick responses to typical and frequently asked questions regarding

Import Channels

Import channels which define load amplitude changes in time.

RSP, RPC and CSV file formats are supported.

In the Project Tree, open the Fatigue SN/EN Time Workbench.
On the workbench toolbar, click (Import channels).
In the window, pick the load history files to be imported.
Click Open.
The imported channels appear in the Project Tree. You can review them by right-clicking on the channel name and picking Edit or simply double-clicking on the channel name.
Note: The Amplitude factor column can be sorted in increasing/decreasing order to understand the min/max load amplitude in a channel.

Imported Channels File Format

CSV file format for importing channels.

CSV file format fields

The CSV file contains one header row and one or more additional data rows. Data values are as follows:

Time - Numeric values. Time points.
Channel name - Alpha-numeric values.
