....is adopted in which edges are meshed first, followed by faces and finally sub bodies. An underlying element size distribution function is assumed to be defined throughout the domain to be meshed. In the case of remeshing, this distribution follows from suitably defined error estimates (e.g. [50]) A preliminary surface mesh is generated byanadvancing front method, with the nodes inserted by hard sphere packing in physical space. The hard sphere packing construction provides a natural means of inserting nodes on a surface in accordance with a prescribed mesh density. Interior nodes are ....
....remeshing, in which case the discretization of the domain is furnished by the old mesh. In all cases, the geometry of the edges is 6 always described by piecewise quadratic interpolation. From the standpoint of mechanics, the local mesh size derives from suitably defined error estimates (e.g. [50]) or other remeshing indicators. However, the local mesh size required to resolve the solution may be too coarse to adequately represent the geometry of the domain of analysis. An example is provided by a solid undergoing a rigid body motion, in which case the size of the mesh is not restricted by ....
