FLUENT-V4 Interface

S

(Return)

The translator creates the FLUENT grid file in either FLUENT V4.0 or FLUENT/BFC Grid File format.

Creating the FLUENT input file

The translator writes the FLUENT input file using a superdomain file, its boundary condition file (boco), and its topology file (topo_mulcad_out). The superdomain file is created using the structured domain files (domain.1 to domain.n) and the topology file (topo_mulcad_out). If structured domain files are selected, they are converted internally to a superdomain prior to run the translator. To create the FLUENT input file, select the translator "FLUENT" in the "Output" menu then select "Write output". You can specify the following options for the FLUENT interface:

• select an existing superdomain file or the structured domain files
• specify the grid file format: FLUENT V4.0 or FLUENT/BFC
• give the name of the boundary condition file
  (default is configuration/parts_mesh/mesh/boco)
• give the name of the FLUENT input file
  (default is configuration/parts_mesh/transfer/fluent)

The interface generates the FLUENT file 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 FLUENT-V4 in MULCAD

Select menu option "ANALYSIS" from the ICEM CFD/CAE MULCAD main menu. Then set the analysis code by selecting:

	-Select  1. MODALS
	-Select  1. ANALYSIS CODE = FLUENT

ICEM CFD/CAE MULCAD offers the following FLUENT specific boundary conditions menu. In this menu, cell type information, boundary condition type and zone number can be specified for domains, subfaces, and edge entities.

• 1. UNSPEC BOUND. COND.
• 2. FLUENT BOUND. COND.
• 3. CONJUGATE
• 4. DEAD ZONE
• 5. INLET
• 6. LIVE CELLS
• 7. OUTLET
• 8. PERIODIC
• 9. POROUS
• 10. PRESSURE
• 11. SYMMETRY
• 12. WALL
• 13. ZONE NUMBER

Defining boundary conditions for FLUENT-V4 in P-CUBE

In addition to the MULCAD-FLUENT Interface, ICEM CFD/CAE supports a P-CUBE-FLUENT Interface:

• Use the boundary condition icons (i.e. Outlet, Inlet, ...) to define
  FLUENT boundary conditions on blocks, faces or edges.
• Use the "Zone #" field to set the zone id.

Defining boundary conditions for FLUENT in the DDN-Mesher Interface

To define boundary conditions to a family in the DDN-Mesher Interface, set the field string1 of the "general bound. cond. menu" to one of the following flags:

	string1		Description
	-------		-----------
	DEAD		dead zone
	WALL		wall
	LIVE		live cell
	OUT		outlet
	INLET		inlet
	CONJ		conjugate
	POR		porous
	PRES		pressure
	SYM		symmetry
	PER		periodic

Note that the boundary conditions "symmetry" and "periodic" can only be assigned to surface or edge. Please refer to the General Remarks section for more details on how to set boundary conditions in the DDN-Mesher Interface.

To define a zone, set string1 to ZONE and enter the zone identification number in the field integer of the "general bound. cond." menu.
