regarding distortion of element in abaqus during meshing

Lucifer
Hi,
     I was trying to mesh a geometry by free meshing with tetrahedron shape. after job submission i found that in warning tab there are 7 distorted element. Will it affect my results after analysis.

Hi Lucifer,

If these distorted elements are away from regions of interest, it should not be a problem.
But to answer to your query, if they affect results? Answer is yes. You will find some change in results compared to an ideal element type.

If the distorted elements are in regions of interest, or in regions with high stress gradients, then yes, they could affect the solution.  However, if the distorted elements are only a small fraction of the mesh, and aren’t clustered together, then the effect could be negligible.  When postprocessing, highlight the element set containing the distorted elements to determine if they’re in a region of interest.  If they are, then you might want to consider remeshing.
