dot product of volvectorfield
How can one get a squared value from volvectorfield? Per say, I have volVectorField A and besides simple output of this in text file I also want to get (and later be able to use) squared value of A in each cell. My first absurd idea was to do pow(A,2), but sadly I don't know the correct answer.
inner product is '&'
volScalarField Usquared = U & U;
