CFD Online Discussion Forums - Question about Accessing a field in time directory

Hi, foamers. I'm modifying the source code of InterFoam for my study.

In the process, I have to access the 'nut', which is the field name in the time directory, and extract the values at a boundary.
So, I used this code.

Quote:

const volScalarField& nut = db().lookupObject<volScalarField>("nut");

But When I tried to compile the code, I got the following error message.

Quote:

‘db’ was not declared in this scope

In case of modifying a boundary condition, the code didn't make any problem.

I'm wondering if there is another way to access a Field in time directory.

Thank you in advance.
