readmesh() void readmesh ( char *  fname, int *  ndim, int *  n, double  x[], double  y[], double  z[], int  ln[], int *  ne, int  ldkc, int  kc[], int  le[], int *  nb, int  ldks, int  ks[], int  lb[], int *  info  ) Read FEM mesh information from FreeFEM++ mesh file Purpose Read FEM mesh information from the file in FreeFEM++ mesh (MEDIT) format. Only the information with the following keywords will be read. Others will be regarded as format errors. MeshVersionFormatted (= 2), Dimension (= 2 or 3), Vertices, Edges, Triangles, Quadrilaterals, Tetrahedra, Hexaedra. Parameters [in] fname Input file name. [out] ndim Dimension (2 or 3). [out] n Number of nodes. [out] x[] Array x[lx] (lx >= n) x-coordinates of nodes. [out] y[] Array y[ly] (ly >= n) y-coordinates of nodes. [out] z[] Arraz z[lz] (lz >= n) z-coordinates of nodes. [out] ln[] Array ln[lln] (lln >= *n) Label numbers of nodes. [out] ne Number of elements. [in] ldkc Leading dimension of the array kc[]. (ldkc >= ns + 1 (ns is the number of nodes in the element)) [out] kc[] Array kc[ldkc*lkc] (lkc >= *ne) Connection matrix: kc[ldkc*(k-1)] is the type of element k, kc[ldkc*(k-1) + 1], ..., kc[ldkc*(k-1) + ns] point to the nodes of element k. The type of element is as follows: = 2: 3-node triangle. = 3: 4-node quadrangle. = 4: 4-node tetrahedron. = 5: 8-node hexahedron. [out] le[] Array le[lle] (lle >= *ne) Label numbers of the elements. [out] nb Number of elements defining boundaries. [in] ldks Leading dimension of the array ks[]. (ldks >= nsb (nsb is the number of nodes in the boundary element)) [out] ks[] Array ks[ldks*lks] (lks >= *nb) Connection matrix of natural boundary sides: ks[ldks*(k-1)] is the type of boundary element k, ks[ldks*(k-1) + 1], ..., ks[ldks*(k-1) + nsb] point to the nodes of boundary element k. The type of element is as follows: = 1: 2-node line. = 2: 3-node triangle. = 3: 4-node quadrangle. [out] lb[] Array lb[llb] (llb >= *nb) Label numbers of the boundary sides. [out] info Return code. = 0: Normal return. = i < 0: The (-i)-th argument is invalid or has an illegal value. = 11: File open error. = 13: Data format error. = 14: Data value error. = 15: Section sequence error. = 16: Unexpected end of file.
