NUMECA Interface

S

(Return)

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 number>
default grid file: configuration/parts_mesh/transfer/configuration.b<block number>.bcs)

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

Limitation

• The ICEM/NUMECA translator supports only 3D grids.
• The user has to check, if the block periodicity information is correct and complete.
• PERNM patches are not supported
