How to Set Beam (B31) offset - Abaqus solver

Hi!
I haven't found any option on Hypermesh regarding 1D Beam offsets.

My goal is to simply translate a rectangular section (B31 - Abaqus) so that the element axis (pink cross) is near the bottom side (red cross):

I tried the *BEAM GENERAL SECTION keyword, creating a general section, but changing the centroid or the shear center isn't what i wanted to obtain. It seems that the moments of inertia are central by default. 

*BEAM GENERAL SECTION, ELSET=<>, SECTION=GENERAL
0.5 ,1.312 ,0.0 ,0.585 ,1.0 ,0.0 ,0.0

*CENTROID
0.0 ,0.264
*SHEAR CENTER
0.0 ,0.2

Thanks for the help! :)

 

P.S. Even if i tried to re-mesh my line component, setting (a) and (b) offsets, it seems that the software doesn't apply them. In the graphic area the created beams are still centered without offsets:

    Hi Sara,

    As of 2019.1, *BEAM SECTION OFFSET in the Abaqus profile was not supported within HyperMesh. Let me check with our team and documentation to see if this is still the case.

    I have just confirmed that the beam section offset in the Abaqus profile is not currently supported, but have also put in a feature request to have this added in 2021.1 release.
