dear all ,

i tried to model just two parts tied by 6 screws and i have this error

The volume of 4 elements is zero, small, or negative. Check coordinates or node numbering, or modify the mesh seed. In the case of a tetrahedron this error may indicate that all nodes are located very nearly in a plane. The elements have been identified in element set ErrElemVolSmallNegZero.

also
if there any way to ignore this 4 element in abaqus ?

thanks in advance

ok,i will do it thanks alot for your concern

RE: elements is zero, small, or negative

Verify the mesh before you run the analysis in the mesh module. In other cases you can get a bad mesh when you run a contact analysis and include the option to remove any initial overclosure. This will change the element shape before the analysis runs even though the mesh passes the verification check. Generally though it's better not to use a tetrahedral mesh as this error is quite common with those elements.
