ERROR # 173 and ERRORS DURING ELEMENT QUALITY CHECK
Hello,
I get two errors in my model. One of them is ''*** ERROR # 173 *** A dependent d.o.f. defined more than once in rigid element entry. GRID ID = xxx component = 1''. I checked my RBE2 elements but I think there is no problem, I can't find the problem. Also, I get ''PROGRAM STOPPED: ERRORS DURING ELEMENT QUALITY CHECK'' error. Then, I review my elements for this error but my tet-collepse is 0. There is no problem for my elements. Where are the mistakes, where am I doing wrong? Please help me, its to important for me.

Altair EmployeeLook at these RBEs.
They share the same nodes, thus leads to an error.
The RBE2 connection requires that the dependent nodes are assigned to only 1 independent node.
When multiple RBEs are created sharing nodes, this is a problem and leads to kinematic incompatibility.
The dependent nodes "don't know" who to follow.
Additionally, concerning the other error:
check for your element quality. there are a few bad elements AND the .out file shows you which ones are not so good.
probably you have 2 RBE elements overlapping. Can you check for duplicated elements? ('check elems' >> duplicates)
Element quality must be verified using 'check elems' too.
