Abstract
For the purpose of Finite Element computation for 2 or 3D geometry, one needs an appropriate mesh of the considered domain. A class of full automatic methods [1] (providing triangles in 2D and tetrahedra in 3D) suitable for any shape, can be seen, after initialization, as the merge of each given point in an updated mesh. The provided mesh, in general, does not fit exactly the boundary (with respect to the edges and the faces) and we suggest a method which satisfies this crucial property.
