The RULES and VARIABLES files can be useful
when editing a CCL file. They provide information on valid options, variables, and
dependencies. Both files are located in <CFXROOT>/etc/
and can be viewed in any text editor.
Note: In some cases, the RULES and VARIABLES
files contain information about variables, parameters, models and options that are
not yet fully supported in the CFX-Solver. Use caution with features that are not
documented elsewhere as these may cause the CFX-Solver to fail or produce invalid
results.
