A mesh improvement methodology is presented which aims to improve the quality of the
worst elements in 3D mesh with non-planar surfaces which cannot be improved using
traditional methods. A numerical optimisation algorithm which specifically targets
the worst elements in the mesh but is a smooth functions of nodal positions is introduced.
A method of moving nodes on curved surfaces whilst maintaining the domain geometry and
preserving mesh volume is proposed and implemented and is shown to be very effective at
improving mesh which traditional mesh improvers cannot improve.
