杆单元和梁单元的连接问题？
浏览：219614 回答：1
当我只用杆单元的时候，模型可以通过；
但当杆梁结合时，模型不收敛；
提示： ***WARNING: SOLVER PROBLEM. NUMERICAL SINGULARITY WHEN PROCESSING NODE 9084
D.O.F. 3 RATIO = 6.2306E+009.
***WARNING: SOLVER PROBLEM. NUMERICAL SINGULARITY WHEN PROCESSING NODE 9163
D.O.F. 3 RATIO = 6.23058E+009.
***WARNING: THE STEP APPEARS TO BEGIN WITH EITHER A RIGID BODY MOTION OR
INSTABILITY AND MAY RESULT IN STABILIZATION DAMPING ENERGY THAT IS
LARGE COMPARED TO THE STRAIN ENERGY. THE DAMPING FACTOR COULD BE
DECREASED FROM THE CURRENT VALUE OF 5.5438E-006.
这个问题该如何解决阿？请大虾们帮帮忙。急！
