Hi,
I am doing analysis of simple shaft with force using inertia relief method.
At ends of the shaft I have formed a spider(multinodal RBE2 element), and have created a suport1 constraint with all translation motion fixed. Point load is applied on the shaft. I have used activated control card param>inrel>-1. Also in sub-case defined Suport1.
When running and its showing error.
INERTIA RELIEF INFORMATION
Reference point : (-0.900000E+03, 0.533992E+01, 0.388932E+01)
*** ERROR # 786 ***
Invalid inertia relief subcase. Its SPC and SUPORT d.o.f. did not
properly remove all the rigid body modes in the model.
The subcase and the redundantly constrained component are:
subcase id = 1
spoint/grid id = 774187
component = 1
This error occurs in module 'asmbdrv'.
Please let me know solution to fix the above error. Thanks in advance..
