(No guarantee) It is a tiny work of a function object to compute Reynolds number.

Might be helpful to someone one day (though not sure).

A minimal example of usage:

ReynoldsNo1
{
    type            ReynoldsNo;
    libs            (fieldFunctionObjects);
    L               1.0;
    writeControl    writeTime;
}

Thank you for sharing that.

In the header file you have mentioned that 'calc' function is to calculate Mach number.

I have a question about the value of dynamic viscosity when the solver is compressible. I don't see in your code where exactly it uses mu instead of nu.

Thank you
