I want to refine the mesh use dynamicRefineFvMesh in dynamicMeshDict, but I don't know how to define the scalar filed of courant number(Co) in controlDict, can you tell me how can I do this? Thanks very much!

Thank you very much for your reply, I am referring to this page to modify the program. There are still some problems, and I am trying to solve

I initially implemented this feature, by setting the functions in controlDict as follow:

functions
{
Co1
{
// Mandatory entries (unmodifiable)
type CourantNo;
libs ("libfieldFunctionObjects.so");
rho rho;
writeControl adjustableRunTime;
writeInterval 1e5;//Do not output the Courant number during the calculation
}
}

And then set the "filed" in dynamicMeshDict as "Co".
