*** INFORMATION #742
The dependent rotational d.o.f. of this rigid element is removed.
RBE2 element id = 9928
independent grid id = 12699
a dependent grid id = 7719
This is because there is no need to constrain the rotational d.o.f. of
any of the dependent grids.
*** INFORMATION #742
The dependent rotational d.o.f. of this rigid element is removed.
RBE2 element id = 9931
independent grid id = 12707
a dependent grid id = 1508
This is because there is no need to constrain the rotational d.o.f. of
any of the dependent grids.
*** 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 2
