PURPOSE

I-DEAS is a program package for the pre- and postprocessing of the FEM (in structural analysis). The generation of the FEM mesh is supported by graphical equipment. The solutions can be plotted. The interface to FEM programs is the universal file.

vemide writes an I-DEAS universal file from the geometrical mesh of the FEM mesh. The elements (except for the nodal elements with CLASS=0) must have a unique element number stored as the first integer vector parameter. The solution is handed over to I-DEAS by the nodal result file, which is created by veid97. Element results (e.g. stresses computed by vemu03) are written to the element result file by veid99. vemide can be called without a preceding vemdis call.

ARGUMENTS

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

Output control flag, normally 1.

0	only error messages are printed.

EXAMPLE

See vemexamples.

METHOD

vemide writes to the universal file on the first process only.

The Nodes

If DIM=3, VEMIDE writes the x-,y- and z-coordinates from the array NOD to the I-DEAS universal file (If DIM=2 or DIM=1, missing coordinates are filled by zeroes).

The Elements

The first integer parameter is the element id number (except for the nodal elements (CLASS=0)). It must be unique, i.e. there exist no different elements with the same element id number. The elements with CLASS=0 create the nodal forces in a load set. The real vector parameters are written to the components of the forces. If NRVP is greater than 6, only the first six vector parameters are considered. Missing values are set to zero.

Dirichlet Conditions

The Dirichlet conditions generate the displacements in special restraint sets. If COMP6=0, the Dirichlet conditions create one restraint set. If NK is greater than 6, only the first six components are considered. If COMP6<>0, the component d creates the d-th restraint set '<d>-th component' which contains all Dirichlet conditions of the component d. The first real vector parameter defines the value of the displacements. Missing values are set to zero.
