BUG: LineSetLoad.Force() for "LOAD_DISTRIBUTION_VARYING" error handling issue

[Dervis-vL]

Describe the bug When creating a LineSetLoad with the Force method and using the enum LineSetLoadDistribution.LOAD_DISTRIBUTION_VARYING as an argument for the load_distribution argument, and providing a list of lists, an error is raised on line 291 of the linesetLoad.py file.

The input for the load_parameter argument according to the documentation is a list of lists:

The lists in the list contain the distance and magnitude.

The data provided is according the documentation: [(0.83, 1.125), (0, 5731.825), (1.67, 1.15), (2.5, 0.75), (2.5, 1.55), (3.33, 1.15), (4.17, 1.15), (5, 0.7), (5, 1.525), (5.83, 1.175), (6.67, 1.175)]

Expected behavior With the input provided I expect the forces to be placed on the lineSet on the provided distance.

Screenshots This is how the object is used:

This is the error message:

Desktop (please complete the following information):

• Version of WIN10 OS: [WIN 10 20H2]
• Version of RFEM6 package version 1.19.5
• Version of RFEM6 is 6.05

Additional context It seems like the error occurs due to faulty error handling in the RFEM package. Line 290 checks if the length of each list is 3, otherwise throw error, but accorsing to the documentation, the length should be 2.

I am also flustered why line 290 says: if len(load_parameter[i]) != 3:

instead of: if len(j) != 3:

Because you are using the enumerate function.

I my opinion either the documentation is wrong or the error handling of the package is. Hope to hear the results soon.

I also seem to be having a struggle doing it in the GUI of RFEM 6.05. MemberSetLoads does not have an issue. LineSetLoads does
