how to change scaler fields to vector field
 
Dear Foamers
I have defined an equation which was scalar ,but right now I want to change it to vector field,how can i do that?
Code:
fvScalarMatrix CEqn
(
    fvm::ddt(C)
  + fvm::div(phi, C)
 ==
    fvm::laplacian(D,C)
);

CEqn.relax();

CEqn.solve();

//C=min(max(0.0,C),1.0);

Hi Ali,

I think a logical first step here would be to attempt to change the word 'Scalar' to 'Vector' in your declarations.
