How ro resolve negative volume elements?

User: "NikhilMyadam26"

Description: Hello. I am working on meshing an assembly of 9 parts using tetrahedral (C3D10) elements on Altair Simlab. I meshed all parts by defining the body mesh controls, creating a surface mesh and then creating a 3D solid tet mesh. I performed the quality check and used Abaqus quality feature, as I want to use this meshed assembly for a calculation in Abaqus. As I performed the quality check and exported the solver input file, I see negative volume elements on one of the parts. The exact error message reads 'Elements failing Abaqus quality criteria found'.
How can I resolve this issue?
Please find images attached for your reference on the quality check parameters I used, and the results I got after cleanup on Dihedral angle and Aspect ratio.
Any help would be very much appreciated.
