✦ Synopsis

ent times the dividing line (shown dashed in Fig. 1b) will be connected with different boundary nodes. It then becomes A structured grid generator based on a new approximation of Dirichlet's functional is developed. An unconstrained minimization necessary to use a remapping procedure between grids of process guarantees that all quadrilateral grid cells are convex at different structures, perhaps at every time step.

The Winslow method [4] and its different generalizations those for the original form of the Winslow method. A generalization for differential and variational formulation have been conto the case of adaptive grids based on harmonic maps between sidered in many papers [1,2,[5][6][7][8][9][10][11][12][13][14][15][16][17]. Direct variational surfaces is considered. ᮊ 1997 Academic Press methods based on the minimization of particular discrete functionals are proposed in [18,19]. Unlike the preceding
