PURPOSE

ISVAS 3 is a program package for the postprocessing of the FEM results. The geometrical mesh and solutions can be plotted. The data are handed over via special files. vemisv writes the geometrical nodes to the node coordinate file and the elements to the element file. The solution is handed over to ISVAS by the variable field file, which is created by veis97. vemdis has to be called before the first call of vemisv.

ARGUMENTS

NAME character*80, scalar, input, local

Nickname of the file. Spaces must not be used.

LIVEM integer, scalar, input, local

Length of the integer information vector, LIVEM>= MESH+ NINFO.

IVEM integer, array: IVEM(LIVEM), input/output, local/global

Integer information vector.

(1)=MESH, input, local

Start address of the mesh informations in IVEM, MESH>203+ NPROC.

(2)=ERR, output, global

Error number.

0	program terminated without error.
90	`LBIG` is too small.
96	unexpected element type.
99	fatal error.

(5)=NIVEM, output, local

Used length of IVEM.

(120)=LOUT, input, local

Unit number of the standard output file, normally 6.

Length of the integer parameter array.

IPARM integer, array: IPARM(LIPARM), input, local

Integer parameter array, see mesh.

LDNOD integer, scalar, input, local

Length of the array of the Dirichlet nodes.

DNOD integer, array: DNOD(LDNOD), input, local

Array of the Dirichlet nodes, see mesh.

LRDPRM integer, scalar, input, local

Length of the real Dirichlet parameter array.

RDPARM double precision, array: RDPARM(LRDPRM), input, local

Array of the real Dirichlet parameters, see mesh.

Length of the array of the node parameters.

NOPARM double precision, array: NOPARM(LNOPRM), input, local

Array of the node parameters, see mesh.

LBIG integer, scalar, input, local

Length of the real work array. The needed length of LBIG depends on the given mesh. A minimal length of LBIG cannot be given. It should be as large as possible.

Real work array.

IBIG integer, array: IBIG(*), work array, local

Integer work array, RBIG and IBIG have to be defined by the EQUIVALENCE statement.

EXAMPLE

See vemexamples.

METHOD

vemisv writes the files on the first process only.

The Nodes

If DIM=3, vemisv writes the x-,y- and z-coordinates from the array NOD (if DIM=2 or DIM=1, missing coordinates are filled by zeroes). Only nodes are written which are referred to by written elements.

The Elements

vemisv writes only the hexahedron, tetrahedron, quadrilateral and triangle elements of order 1 and order 2. Since ISVAS 3 processes only one type of elements, only the elements in the mesh with the maximal number of geometrical nodes are written.
