creating a perfect spherical hole in an orphan mesh (Abaqus)

[Prithivirajan]

Hello All,

I have an 3D orphan mesh (Abaqus) that I obtained from the Gmsh software. I would like to insert a perfect spherical hole in that mesh.


I selected all the elements inside a sphere and deleted them but i am getting a very coarse surface, look at the figure attached

Is there a way to create a perfect spherical hole in a 3D Abaqus mesh ( I do not have the part geometry) ?


I thought something like, smooth the inside of the surface of the mesh deletion, but I donot know how to do that.
