Matlab有限元网格化源程序-distmesh2d.m MIT的人写的论文,一个简单的有限元网格化方法 确实可以用,但是我理解的不是很好。 不过,希望对需要的人有所帮助。 简单介绍: function [p,t]=distmesh2d This meshing function produces the following outputs: • The node positions p. This N-by-2 array contains the x, y coordinates for each of the N nodes. • The triangle indices t. The row associated with each triangle has 3 integer entries to specify node numbers in that triangle. The input arguments are as follows: • The geometry is given as a distance function fd. This function returns the signed distance from each node location p to the closest boundary. • The desired edge length function h is given as a function fh, which returns h for all input points. • The parameter h0 is the distance between points in the initial distribution p0. For uniform meshes = constant), the element size in the final mesh will usually be a little larger than this input. • The bounding box for the region is an array bbox=[xmin, ymin; xmax, ymax]. • The fixed node positions are given as an array pfix with two columns. • Additional parameters to the functions fd and fh can be given in the last arguments varargin .
