BEAMCOLUMNJOINT

[payam asadi]

hi dear sir/madam!
I make a one story one bay RC frame from your examples and added beamcolumnjoint to this model, like your example in manual, but when I run static gravity load opensees reply error message as: "warning bangenlinlapack solver :: solve <> -lapack routine returned 2.
warning newtonraraphson:: solvecurrent step <> -the linear sys of eqn failed in solve <>staticanalysis ::analyze <> -the algorithm failed at iteration :1 with domain at load factor 0.2
opensees > analyze failed , returned : -3 error flag
model built"
what can I do for solve this problem and what is the era of this error?
