i have an axisymetric mesh with wedge boundary condition now i like to calculate Ur and Uteta , once i saw we can convert Cartesian coordinate system into cylindrical coordinate but it seems it does not work in openFoam 1.6.x , this function is protected type

cylindricalCS ccs
(
"ccs",
vector(0, 0, 0), // center point of ccs
vector(0, 0, 1), // axis of ccs
vector(1, 1, 0) // base axis for cylindrical angle
);

vectorField Uint = U.internalField();
vectorField Ucyl = ccs.globalToLocal(Uint,false); //error line!!!


error: virtual Foam::tmp<Foam::Field<Foam::Vector<double> > > Foam::cylindricalCS::globalToLocal(const Foam::vectorField&, bool) const is protected

now is there any suggestion how i can access to Ur and U tetha?

check out this thread:

bug in cylindricalCS class or fatal setup error?!!

Your coding is a bit different in my code, could do the trick. However I wrote it for 1.7.

thank you for ur interest i will look ur code and inform u, could u visualize stream line for a wedge type axisymmetric mesh? streamFunction only work for 2D case.

hi
can you tell me where and how should I apply cylindricalcs ? I really need that .

Special Thanks
