Reply To: Error in meshing which says,”One or more entities failed to mesh.”

Hi Mukta,
Thanks for your patience. I am not sure if you are still working on this issue. 
I hope you selected the 'not-merged' face option while converting the facets into a solid body in SpaceClaim. If this still highlights the same error, you can try importing the faceted geometry directly into the mechanical software without converting it to a solid first. Then, use patch-independent tetrahedral meshes and see if the mesh error persists in the mechanical software Also, turn capture curvature & capture proximity to “YES”, you will find those options under the sizing. 
Please let me know if it works for you or not. 

I am not sure what type of meshing method you followed while generating the mesh previously. 

Best Regards,
Sampat
