Greetings Aiyu and welcome to the forum!

With the help of Google and the source code documentation ( http://foam.sourceforge.net/docs/cpp/index.html ), here's what I found:
I suggest that you study the tutorials that OpenFOAM provides, where there are several examples of how "nut" and "nuTilda" are defined. You can find these tutorials by running:
Code:

find $FOAM_TUTORIALS -name nut
find $FOAM_TUTORIALS -name nuTilda


Best regards,
Bruno
