writegmsh22() def writegmsh22 ( fname  , n  , x  , y  , z  , ne  , kc  , lb    ) Write FEM mesh information to Gmsh file Purpose Write FEM mesh information to the file in Gmsh format (Version 2.2). Returns info (int) = 0: Successful exit. = i < 0: The (-i)-th argument is invalid or has an illegal value. = 11: File open error. = 12: Invalid element type. Parameters [in] fname Output file name. [in] n Number of points. [in] x Numpy ndarray (1-dimensional, float, n) x-coordinates of nodes. [in] y Numpy ndarray (1-dimensional, float, n) y-coordinates of nodes. [in] z Numpy ndarray (1-dimensional, float, n) z-coordinates of nodes. [in] ne Number of elements of FEM (including boundary elements). (ne >= 1) [in] kc Numpy ndarray (2-dimensional, int32, ldkc x ne) (ldkc = nn + 1 (where nn is the number of nodes in the element)) Connection matrix: kc[k, 0] is the type of element k, kc[k, 1], ..., kc[k, nn] 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. = 11: 10-node second order tetrahedron. = 12: 27-node second order hexahedron. = 13: 18-node second order prism. = 14: 14-node second order pyramid. = 15: 1-node point. = 16: 8-node second order quadrangle. = 17: 20-node second order hexahedron. = 18: 15-node second order prism. = 19: 13-node second order pyramid. = 20: 9-node third order incomplete triangle. = 21: 10-node third order triangle. = 22: 12-node fourth order incomplete triangle. = 23: 15-node fourth order triangle. = 24: 15-node fifth order incomplete triangle. = 25: 21-node fifth order complete triangle. = 26: 4-node third order edge. = 28: 6-node fifth order edge. = 29: 20-node third order tetrahedron. = 30: 35-node fourth order tetrahedron. = 31: 56-node fifth order tetrahedron. = 92: 64-node third order hexahedron. = 93: 125-node fourth order hexahedron. [in] lb Numpy ndarray (2-dimensional, int32, ldlb x ne) (ldlb = nlb + 1 (where nlb is the number of labels for the element)) Label numbers of the elements: lb[k, 0] is the number of labels for element k, lb[k, 1], ..., lb[k, nlb] are the labels for the element k.
