Constrain/connector between deformable part and analytical rigid body ABAQUS.

Dear all,

I am trying to assign CONSTRAINT and CONNECTOR ELEMENT to my ABAQUS/STANDARD model, spent 2 days without any progressing, the problem I have is that, the system does not seem to recognize the connector or constraint I put between a defomatble part and a rigd body tooling.

I started wondering that, would it be not possible to assign constraint or connector element to rigid body?

 Many thanks in advance.

cheers,

Jason
