rotational stiffness units

[legersalazar]

what are the units for rotational stiffness in FEMAP?

specifically the angle units, rad or deg?

thanks,

I've been using Femap and Nastran for decades, but don't remember this on the spot. It's likely to be moment per radian, because it is a direct "Nastran" entry, rather than being just a Femap model building activity (such as rotating some geometry, which uses degrees). But wouldn't the easiest way to answer a question like this be to build a simple test model? If someone asked this of us as a support question, that's what we would do if we weren't 100% sure. Or look at the docs (Quick Reference Guide), which will have the answer for the element type you've chosen.
