HI all, I'm new here.
I have some warning (negative eigenvalues;Solver problem. Zero pivot when processing D.O.F.)
in my model because i don't know how to link truss and beam elements(maybe in the node of contact?).My part look like a cage of 1D elements of steel( all elements are continuous).
I need some help please, thanks :)
