writevtkug() void writevtkug ( char *  fname, int  n, double  x[], double  y[], double  z[], int  ne, int  ldkc, int  kc[], double  u[], int *  info  ) Write coordinates and their values to VTK (Solution of PDE by FEM) Purpose Write solution of PDE by FEM to the VTK file (including mesh information). Parameters [in] fname Output file name. [in] n Number of points. [in] x[] Array x[lx] (lx >= n) x-coordinates of nodes. [in] y[] Array y[ly] (ly >= n) y-coordinates of nodes. [in] z[] Arraz z[lz] (lz >= n) z-coordinates of nodes. [in] ne Number of elements of FEM. (ne >= 1) [in] ldkc Leading dimension of the array kc[]. (ldkc >= ns + 1 (ns is the number of nodes in the element)) [in] 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: = 1: 2-node line. = 2: 3-node triangle. = 3: 4-node quadrangle. = 4: 4-node tetrahedron. = 5: 8-node hexahedron. = 6: 6-node prism. = 7: 5-node pyramid. = 8: 3-node second order line. = 10: 9-node second order quadrangle. = 15: 1-node point. [in] u[] Arrau u[lu] (lu >= n) Values at the points. [out] info Return code. = 0: Normal return. = i < 0: The (-i)-th argument is invalid or has an illegal value. = 11: File open error. = 12: Invalid element type.
