Yes. The finite octree method for INITIAL mesh generation may be good. There is  
also sufficient work-in-progress in the area of Delaunay triangulation. Refer  
to Dr. Sheppard's comprehensive summary of mesh generation techniques for more  
information on mesh generation procedures. 

This is not what I want to share. FEM's success partially depends on the  
quality of the mesh used for analysis. It is imperative to possess sufficient  
knowledge about the model to adequately represent an area or domain of high  
singularity. That is where adaptive remeshing is good. Several papers published  
have proven the capability of h-p analysis methods. I believe, so far no  
commericial code carries the h-p procedure. I might be wrong! Any idea?
