CFX Command Language (CCL) consists of commands used to carry out actions in CFX-Pre, the CFX-Solver Manager and CFD-Post. All of the steps carried out in CFX-Pre are executed as CCL commands in the software’s engine, and these commands can be exported and imported to other cases.
Tip:
You can also import expressions and regions using the Import CCL command.
To import composite region definitions from older versions of CCL, use the Import CCL command found in the File menu, rather than the import command found in the Regions workspace.
A useful application of importing CCL is to apply the same preprocessing data to a number of different meshes. In such a case, the following general workflow may be ensued:
Import the new mesh.
Import the CCL data.
Assign mesh locations to the domains and boundary conditions, if required.
Write the CFX-Solver input file for the CFX-Solver.
The benefit of using this workflow is that there would be no need to specify all of the preprocessing data again.
Importing a set of commonly used customized material or reaction definitions is also possible by importing a CCL file. A useful application of the import CCL feature is demonstrated when using Library Mode. For details, see Library Objects.
