Hi all,
I have a question about fvOption. I am using meanVelocityForce as the type of momentum source in my fvOption file. However, by looking the source file of this momentum type at OpenFOAM-5.x/src/fvOptions/sources/derived/meanVelocityForce, something seems hard to me.

https://github.com/OpenFOAM/OpenFOAM...ityForce.C#L89
We have a Ubar_ vector as a protected value which is read from fvOption file. Due to its protected type, it cannot be used at the outside of its class. So can anybody help me to just print its value (Info) at each timestep of my solver.
I think a solution is defining a public function at the class to print its value, and use this function at each time step in our solver coding (fvOptions.functionforUbar). But it has lots of c++ details.
