INT_BEAM, typo in Manual, bad response for ISECT=2, NITR=2

[SonSiont]

Describe the bug
The bending moment in a beam should be the inverse of the reaction moment.
With INT_BEAM, ISECT=2, NITR=2 section, there is a high deviation.
The Radioss Reference Guide has in the description /ANIM/BEAM maybe a typo for the plastic strains.

To Reproduce
Run the model and compare the bending moment of element 2111 as in the figure in the attached pdf.

Expected behavior
Correction of the manual regarding EPSP vs. ESPN/N. Extent the section description, give a warning in
the manual for the mentioned plastic beam.

Output
A pdf file with detailed explanations and the Radioss files are in the archive.

Desktop (please complete the following information):

• Version 6cf5b43
• Hardware Intel
• Configuration SMP with one thread
