You can edit the CCL definition of a CFX-Solver input file while the solver is running. The changes you make take effect when saved and the modified CCL is pre-processed for the flow solver. The modified CCL may take several iterations to be updated depending on system load, hardware and problem size.
These changes apply only to the run in progress, and do not affect the CFX-Solver input
file that was used to begin the run (if one was used). Before the next outer-loop
iteration begins, a backup file named
<iteration number>.bak is written to the working
directory. The backup file can be used to restart the run from the point at which the
CCL definition was changed, if needed.
Only selected CCL parameters can be dynamically changed. A list of these parameters is in the RULES file. For details, see RULES File.
The Command File Editor can also be used to make changes to the CCL contained in a CFX-Solver input file. Changes, when saved, affect the edited CFX-Solver input file only, not any run in progress. For details, see Editing CFX-Solver Input Files.
To access the command file editor, select Tools > Edit
Run In Progress or click 
.
Note: The Edit Run in Progress command is not available for simulations involving any of the following features:
Transient Blade Row Modeling
System Coupling
Dynamic Variables.
Note: You must not change any references to regions while the CFX-Solver is running with topology simplification active; doing so would cause the solver to stop.
For details on topology simplification, see the description for expert parameter topology simplification in
Physical Model Parameters in the CFX-Solver Modeling Guide.
