The NUMECA interface creates grid files and boundary condition files
of a structured grid in IGG file format.
Creating the NUMECA (IGG) files
The translator writes the IGG files using the structured domain files (domain.1
to domain.n), the boundary conditions file (boco) and the topology file
(topo_mulcad_out). To create the IGG files, select the translator "NUMECA"
in the "Output" menu from the ICEM CFD/CAE Manager. After clicking "Write
output" you can specify the following options for the NUMECA interface:
select the domains to include in the IGG files
give the name of the topology file (default is configuration/topology/topo_mulcad_out)
give the name of the boundary condition file (default is configuration/parts_mesh/mesh/boco)
option to create ascii grid files (default is binary)
give the name of the IGG files
(default grid files: configuration/parts_mesh/transfer/configuration.b<block
default grid file: configuration/parts_mesh/transfer/configuration.b<block
After clicking "Done" the interface generates the NUMECA files located
in the Transfer Shell. You may open a shell window in this directory by
selecting the menu items "Utility" and "Transfer Shell".
Defining boundary conditions for NUMECA
The program supports the following boundary condition flags for faces:
SOL, INL, OUT, EXT, MIR, SNG, ROT
MULCAD DDN-Mesher P-CUBE

1.FLAG 1.string1 NAME field Enter a boco flag from the list above
The ICEM/NUMECA translator supports only 3D grids.
The user has to check, if the block periodicity information is correct
