What is 1D Element Force for CBEAMs in non-linear static analysis

Hello,

I am having trouble understanding what 1D Element Force in HyperView is providing for cbeams. In particular for a L section cbeam element without offsets in a non-linear static analysis when load is not applied at the centroid. I would have expected the 1D Element Force to be equal to the FBD of the same element but they differ. What info does 1D Element Force give that I am not fully understanding?

See model and results below. Thanks in advance.

Version: 2024.1

Hello,

I have tested with versions 2025, 2025.1 and I get consistent results for the L-section Beams

Thanks for your reply. While I do not have 2025 or 2025.1 I tested with 2022 and 2022.3 and the results match what 2025/2025.1 give. Just for completion I have attached the last time step from the 2024.1 .force results below.
