Abaqus How to show the coordinate system of beam elements in visualization window?

[Fblthp]

Hi all

For beam elements, I heard that results directions (such as U1\U2\U3) are given in the assigned beam section orientation (please confirm me this). This coordinate system would once display while I assign the beam section orientation to any set in property window. Now I want to show them in visualization window, how can I do that?
In fact, I do the orientation assignment using python scripts. The orientation was assigned to an element set instead of a geometry set. For the assignment on geometry set, at least I can show the local coordinate system at Property-Tools-Query-Beam Orientations. It seems unable to show for the assignment on element set.

Only element outputs (such as stresses, strains and section forces) are given in local coordinates. Displacements are in global coordinates.

Thank you for your answer FEA way

I want to obtain a field of parameter trying to characterize nodals or elements stiffness in a simple approach. By simple approach I mean not trying to obtain the stiffness matrix. Now I come out a way of parameter=SF/U, SF and U are supposed to be in same direction. However the U and SF are not in the same direction. If U is in global coordinate, can I obtain the transformed U in the local coordinate.
And, please give any opinion on my approach?

Just notice the NFORC result. Is NFORC in global coordinate system? Then maybe I use NFORC/U is more appropriate?

You can transform the results to a common user-defined (local) coordinate system. But check the post titled "How to create stiffness (nodal force/displacement) contour plot using Python script in Abaqus?" on Stackoverflow too.
