(Return)

The CFX-TASCflow interface translates the output from ANSYS ICEM CFD/CAE to a grid file and a block-off & boundary conditions file according to the CFX-TASCflow Database Interface Version 2.3.1 (May 1994). These output files can be read by all versions of TASCFlow from Verson 2.3.1 to Version 2.10.

Creating the CFX-TASCflow Input Files

The translator writes the CFX-TASCflow input files using the multiblock structured mesh files, the boundary condition file and the topology file. To create the CFX-TASCflow input file, select the translator "CFX-TASCflow" in the "Output" menu. After clicking "Write input", you can specify the following options for the CFX-TASCflow output interface:

select ASCII or Binary format: The bcf file must always be formatted so this option applies only to the grid file.
give the name of the topology file
give the name of the boundary condition file
give the prefix for the CFX-TASCflow input files (default is tascflow, which result in files tascflow.grd and tascflow.bcf)
option to give a scaling factor for each direction (default is 1.0)

The interface generates the CFX-TASCflow files located in the project directory. Note that a file called name.lun is created in the same directory while running the translator.

Defining blocked-off elements and regions

Additional Blocked-off Flux Elements:

Please refer to the General Remarks section for information about boundary condition definition.

By default all subgrids (blocks) are composed of fluid flux elements. To define a blocked-off flux domain, select a block and click on "Additional Blocked-off Flux Elements", in the boundary condition GUI window.

Regions and Subregions:

A nodal region is a list of one or more subregion(s) having the same identification label. A subregion consists of a given range of i, j, k coordinates on a particular subgrid (block or domain). To define a subregion, select an edge, a surface or a block family, then click on "Regions and Subregions" option in the boundary condition GUI window. This opens a field where the subregion label can be defined. The label is currently limited to 5 characters. All subregions with the same label are grouped into the same TASCflow region.

Limitations

The CFX-TASCflow Database Interface (TDI) accepts mono or multiblocks grids in 3D.
