writevtkug() def writevtkug ( fname  , n  , x  , y  , z  , ne  , kc  , u    ) Write coordinates and their values to VTK file (Solution of PDE by FEM) Purpose Write solution of PDE by FEM to the VTK file (including mesh information). 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. (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. = 15: 1-node point. [in] u Numpy ndarray (1-dimensional, float, n) Values at the points.
