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: 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.
