Hello all
I want to average my velocity field, and save it in another field called Uave. To do this, first I create Uave;

volVectorField Uave(U);
Uave = 0.0*Uave;

Now, we have Uave. Then I averaged U to get Uavex, Uavey, Uavez;

Uavex = gAverage(U.component(0))
Uavey = gAverage(U.component(1))
Uavez = gAverage(U.component(2))

My main question is that how to put Uave =(Uavex,Uavey,Uavez). Since one side is dimensioned and othe is just a scalar. Also, sizes are not equal. What should I do?

Thanks,
Farzad

Hello. I don't fully understand. The result of the average of U_X is a scalar as you said. Thus you get 3 scalars finally. You can store them in a vector if you like


vector Uave = vector(Uavex, Uavey, Uavez);


but I don't see how to transform this in a "field".
