Hello everone , when i runing my job in abaqus , I am getting error like following .
The volume of 5 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. Analysis Input File Processor exited with an error.
What should I do? Please guide me
Thanks
I think this conversation thread can help you a lot, it consists of all the possible reasons at per my knowledge.

Along with that, go for mesh verify to assess the quality of mesh as complex geometry is prone to such error with default meshing scheme.
Hi ram
The error message you received means that some of the elements in your mesh have a very small or negative volume, which is not acceptable for the analysis. This can happen due to various reasons, such as:
- The coordinates or node numbering of the elements are incorrect or inconsistent.
- The mesh seed is too large or too small for the geometry or the boundary conditions.
- The elements are tetrahedrons that are very flat or degenerate.
To fix this error, you can try the following methods:
- Check the coordinates and node numbering of the elements and make sure they are correct and consistent. You can use the Abaqus/CAE tools to verify and edit the mesh.
- Modify the mesh seed and adjust the element size and shape. You can use the Abaqus/CAE tools to refine or coarsen the mesh, or use different meshing techniques or algorithms.
- Identify and delete the elements that have zero, small, or negative volume. You can use the Abaqus/CAE tools to create a display group of the elements that belong to the element set ErrElemVolSmallNegZero and remove them from the mesh.
