*** INFORMATION # 741
No need to constrain the rotational d.o.f. of this dependent grid.
    RBE2 element id = 3677024
independent grid id = 4464355
   dependent grid id = 4464354
This is because there isn't any stiffness and load on the rotational
d.o.f. of the dependent grid.
*** INFORMATION # 743
The total number of grids whose rotational d.o.f.s need not be
constrained in RBE2 elements is 14.

*** INFORMATION # 743
The total number of rigid elements, whose rotational dependent d.o.f.
are removed because there is no need to constrain those d.o.f., is 1977.

*** INFORMATION # 744
The number of autospcs that will be created to remove the rigid body
rotation in RBAR and RBE2 is 323.
这些都是什么意思，是我weld单元建错了，还是刚性单元grid约束加多了？

把RBE2刚性单元约束了转动自由度
The total number of grids whose rotational d.o.f.s need not beconstrained in RBE2 elements is
