Geometry Cleanup:

1. Check for any geometry abnormality like missing fillet , surfaces, duplicate surfaces, open faces etc.
2. Correct the geometry wherever possible as per requirement & run auto clean command

Criteria Setup:

Go to Preference>> Criteria file setting>> set the requisite criteria for meshing
