If activated under General an additional input page for the load spectrum is available.
The first column 'Frequency' needs to sum up to one (or less) for all load spectrum elements. Additional columns can be added using the context menu with the right mouse button.
Rows can be added using the -button or a selected row can be deleted using the -button. The -button clears all the inputs.
Using the -button, the load spectrum is read from a file. The columns that are currently shown with its units have to be used for the input file. As the data from the file is added to the inputs, you must clear the inputs first to define a full load spectrum. Likewise, a created load spectrum table can be exported with the corresponding -button.
