Hi I am new in C++ so I dont know the structure database used in openFoam. The problem I am facing is typically a programming language problem. I dont know the correct command for my purpose. Any help will be deeply appreciated.

The above is a code for MapConsistentVolField.H, I have issue with the line highlighted/underlined. In that line the "fields" is suppose to take list of all the variables like P,T for classtype volScalar. How can I check that list of variables stored in fields.

I am trying commands like fields.lookup(name) to know the name of the variables that is in the list of fields. It is showing error "MapConsistentVolFields.H:56:52: error: no matching function for call to ‘Foam::IOobjectList::lookup(<unresolved overloaded function type>)’". what is the correct command for this purpose?
