at least one of the nodes of the connector element does not have any mass associated with it.

at least one of the nodes of the connector element does not have any mass associated with it.

(OP)
I have been getting this warning message in my model. And solution in not converging at all. Please guide me on how to resolve this.


AT LEAST ONE OF THE NODES OF CONNECTOR ELEMENT 1 (ASSEMBLY) DOES
NOT HAVE ANY MASS ASSOCIATED WITH IT. THIS COULD LEAD TO EQUATION
SOLVER ISSUES (ZERO PIVOTS, NUMERICAL SINGULARITIES, etc.) AND
HENCE TO INCORRECT SOLUTIONS WHEN THE CONNECTOR ELEMENT IS
ENFORCING KINEMATIC CONSTRAINTS (FROM EITHER INTRINSIC, CONNECTOR
STOP/LOCK, or CONNECTOR MOTION). PLEASE ATTACH THE CONNECTOR NODES
TO ELEMENTS FOR WHICH MASS IS DEFINED (SUCH AS ELEMENTS TYPE MASS
WITH A SMALL MASS) TO RESOLVE THE PROBLEM.

Thanks in advance,
SAchin

RE: at least one of the nodes of the connector element does not have any mass associated with it.

Open the .odb in the visualization module in Abaqus/CAE. Then use the Display Group tool to locate element #1 and think about the two attached nodes and if they have mass. Otherwise assign a point mass in the interaction module.
