When solving CFX models remotely, there may be situations where a user may wish to change certain input parameters to a CFX definition file without having to launch CFX-Pre. Although the CFX .def definition file is a binary file, changing input parameters can be accomplished by extracting the CCL (CFX Command Language) statements to a text file. The input can then be read and edited, as needed.

The cfx5cmds executable is located in the same “bin” directory as cfx5solve and other CFX executables. The syntax can be viewed by running cfx5cmds -help. Essentially, one would use the following command to extract the CCL parameters from “myrun.def” to “myrun.ccl”:

cfx5cmds -read -def myrun.def -text myrun.ccl

Once editing of the text file “myrun.ccl” is complete, the definition file is updated via the following:

cfx5cmds -write -def myrun.def -text myrun.ccl

The user can then rerun the new analysis with cfx5solve using the updated definition file.

It is useful to note that this is the manner in which CCL-only beta features would be defined.
