CFX-TASCflow offers its own meshing facilities, which are collected in the CFX-TASCgrid module, and which can be used to generate structured computational grids. Those grids are generally boundary-fitted and can be non-orthogonal and curvilinear too. Specific meshing datas are then written to a grid file.

The process of generating a grid breaks down into four phases which correspond to the four CFX-TASCgrid modules contained in the CFX-TASCflow software. The information is entered in text format, and is processed then using those modules :

 

     

  • Geometry Phase (CFX-TASCgridg)

The GDF file defines the physical curves and surfaces of the problem.

 

  • Curve Phase(CFX-TASCgridc) : 

The CDF file contains the (i,j,k) location of each labeled vertex and the node distribution specified for each curve segment.

 

  • Surface Phase (CFX-TASCgrids) : 

The SDT file distributes nodes on each surface betweenthe nodes already distributed on the bounding curves.

 

  • Interior Phase (CFX-TASCgridi) : 

The IDF file distributes nodes in the interior.

 

Once defined, the grid has to be checked using CFX-TASCtool. This checking is required both to ensure that there are no excessively skewed elements and to calculate the control volume sizes.

Unfortunately, as said in the introduction, no grid has been generated for this first approach.
