Meshfree CAD Design and Solid Remolding

In the recent issue of Mechanical Engineering (May, 2006), Jean Thilmany, one of the associate editors of the journal, wrote an article, No Mesh, No Fuss, to introduce the next generation of CAD design and solid remodeling ---- the meshfree CAD design.

By throwing away the mesh, the latest meshless CAD design is claimed being faster, more efficient, and representing the future trend. So after all, meshfree methods are thriving in major engineering applications (Read more .... ).

I took a look at this, and it appears quite similar to the isogeometric work that Tom Hughes and colleagues introduced at UT Austin in 2004. I believe a series of papers on the topic have recently appeared.

The basic idea of the method is to use the same functions that describe the geometry as a basis for a Galerkin method. In fact the method does rely on a mesh for integration, so it is not exactly a meshfree method. In this case, however, the mesh exactly conforms to the geometry, whereas in the FEM the mesh only approximates the physical geometry.

Thanks for the information.
Nevertheless, do you think that is it
possible to have truly meshfree CAD
design in the future ?
If it is possible, it will change
the engineering design forever.
