SUMMARY
The discussion centers on computing the flux integral over the walls of a cylinder oriented along the z-axis using the vector field \(\vec{F}\) and the gradient of the function \(G(x,y,z) = r^{2} = x^{2} + y^{2}\). The gradient is calculated as \(\nabla G = <2x, 2y, 0>\). While one participant suggests using the Divergence Theorem for a more straightforward solution, the original poster seeks to compute the flux integral directly without employing the theorem. The discussion confirms that the proposed method is valid for calculating the flux integral over the cylinder's walls.
