Nastran CBEAMs Orientation warning msg

prasad.guduguntla.external over 4 years ago

Hello

I got a warning message about the orientation of CBEAMs (Nastran 2019)

*** USER WARNING MESSAGE 5487 (EBEMS)

ORIENTATION VECTOR DEFINED FOR THE ELEMENT ID =47505366 IS NEARLY PARALLEL, IT MAY GIVE POOR RESULTS.

In the previous versions, Orientation vector collinear with the element axes - these leads to FATAL ERROR

What effect will have it on displacements and element forces?

Thanks in Advance

Prasad.

No matter what the results are, it's a poor practice to define orientations that are close to parallel with the element. I don't know why anyone would want to...it would make it very difficult for another user to figure out if the orientations are defined correctly.
