Dear all,

I woul line integrate e gradient moltiply to a vector. I will try to explain better.

I have define this function:

$phi(xi,eta)=(2*xi-1)*(xi-1)*(2*eta-1)*(eta-1)$

and I have a vector a

v=(0,1)

I would like to applu a dot product between the gradient of phi an the vector and integrate the results.

I have already try in many way but without succeed. Someone could please help me?

Thanks
