-ndf

Post by im_pce »

Dear friends

I had a question and I would be grateful if you could answer me.
I am trying to model a 3-D structure that some elements are truss and some of them are frame elements. Since for truss: ndm=3 ndf=3 and
for frame: ndm=3 ndf=6, what is -ndf in " model BasicBuilder -ndm 3 -ndf ? " for this structure ?

Thank you.

the truss can handle 6 dof/node, use ndm=3 ndf =6 for both.
