PURPOSE

vemu01 is a routine to print the FEM mesh to unit LOUT. The user can specify which informations to print: general mesh informations, coordinates of the geometrical nodes, elements or Dirichlet conditions. Additionally the user can specify where the informations are to be printed. Each process prints its part of the mesh, or the first process (logical number 1) prints the meshes on all processes. In the second case there is the option to compose the meshes on the processes into a global mesh so that the distribution of the mesh onto the processes is not shown. vemu01 can be called without a preceding vemdis call.

ARGUMENTS

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.
0program terminated without error.
90LBIG is too small.
95IVEM is too small.
99fatal error.
(5)=NIVEM, output, local
Used length of IVEM.
(20)=LOUT, input, local
Unit number of the standard output file, normally 6.
(21)=OUTCNT, input, local
Output control flag. A number of four digits indicates which parts of the mesh are to be printed. 

1 1 1 1  
| | | -- print Dirichlet conditions
| | ---- print elements
| ------ print coordinates of the geometrical nodes
-------- print mesh informations
So OUTCNT = 1000 prints only the mesh informations, OUTCNT=0101 prints the coordinates of the geometrical nodes and the Dirichlet conditions,... OUTCNT=0 gives no output.
(22), input, global
0The mesh on each process is printed by the respective process.
1The mesh is printed on process 1, the distribution is shown.
2The mesh is printed on process 1, the distribution is not shown.
(200)=NPROC, input, global
Number of processes, see combgn.
(201)=MYPROC, input, local
Logical process id number, see combgn.
(202)=NMSG, input/output, global
Message counter. The difference of the input and the output values gives the number of communications during the vemu01 call.
(204)=TIDS(1), input, global
Begin of the list TIDS which defines the mapping of the logical process ids to the physical process ids. See combgn.
(MESH), input, local
Start of mesh informations, see mesh.
LNEK integer, scalar, input, local
Length of the element array.
NEK integer, array: NEK(LNEK), input, local
Array of the elements, see mesh.
LRPARM integer, scalar, input, local
Length of the real parameter array.
RPARM double precision, array: RPARM(LRPARM), input, local
Real parameter array, see mesh.
LIPARM integer, scalar, input, local
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.
LIDPRM integer, scalar, input, local
Length of the integer Dirichlet parameter array.
IDPARM integer, array: IDPARM(LIDPRM), input, local
Array of the integer Dirichlet parameters, see mesh.
LNODN integer, scalar, input, local
Length of the array of the id numbers of the geometrical nodes.
NODNUM integer, array: NODNUM(LNODN), input, local
Array of the id numbers of the geometrical nodes, see mesh.
LNOD integer, scalar, input, local
Length of the array of the coordinates of the geometrical nodes.
NOD double precision, array: NOD(LNOD), input, local
Array of the coordinates of the geometrical nodes, see mesh.
LNOPRM integer, scalar, input, local
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.
RBIG double precision, array: RBIG(LBIG), work array, local
Real work array.
IBIG integer, array: IBIG(*), work array, local
Integer work array, RBIG and IBIG have to be defined by the EQUIVALENCE statement.
