(OP)
Hallo everybody,

I would like to know how to make a contact with a plate and a line with rigid elements. The erroro message says me that some elements are not defined. Such elements are that one of the line, but they are rigid elements. Which kind of properties I should apply?

Thanks,
Albert

RE: contact

rigid element don;t need any meshing, they are not deformable and E is infinity

RE: contact

(OP)
the message error is the following:

ABAQUS/CAE will not generate a mesh or any attributes (such
as loads, boundary conditions, etc.) for unmeshed regions.
The job input file "contact.inp" has been submitted for analysis.
Error in job contact: in keyword *RIGIDBODY, file "contact.inp", line 10004: Unknown assembly set _PICKEDSET56
Error in job contact: ELEMENT SET ASSEMBLY__PICKEDSET56 HAS NOT BEEN DEFINED

did I miss something else?

RE: contact

If you want to define a component as rigid, you have two options;

1) Mesh the part with rigid elements (R2D2, R3D3 etc...).
2) Define the part as analytical rigid.  This assumes that the profile can be defined using lines and arcs.

See the ABAQUS Users Manual section 2.3.4 for guidance on defining analytical rigid surfaces.

As for rigid elements, you can mesh parts with these as you would other structural elements.  Look up section 24.3.1 for info on rigid elements.

As to the problem with your analysis, it looks as if you have an unmeshed part - presumably this is the part that you require to be rigid.  You will need to go back to the Meshing module, mesh the part and make sure that you assign a rigid element property to the part.
