A dependent d.o.f.
Altair EmployeeDear all,
I kept getting the error and can't figure out the problem. Can anyone help please... Thank you first.
Basically, my system is set as this. I would like to allow my model to rotate but constrained by other point.
*** ERROR # 176 ***
A dependent d.o.f. of rigid elements is constrained in an SPC set.
grid id = 1741329
component = 5
SPC set id = 45

Altair EmployeeThank you, Tin,
So how can I fulfill my goal to constrain the model? I would like to release the model one rotation DOE and constrain the rotation by the displacement of one the other node? like the figure below. Thank you!
Thanks,

Altair EmployeeHi @Edison
You can either try with RBE3 or use zero-length spring elements to constraint and attach the same to RBE2.
Hi,
the 2-end RBE2 must not be constrained at both ends, because one has been 'dependent' on the alternative
