We present new second-order prolongation and restriction formulas which preserve the divergence and, in some cases, the curl of a discretized vector field. The formulas are suitable for adaptive and hierarchical mesh algorithms with a factor-of-2 linear resolution change. We examine both staggered ...
The divergence of a vector field is a scalar function. Divergence measures the “outflowing-ness” of a vector field. If vv is the velocity field of a fluid, then the divergence of vv at a point is the outflow of the fluid less the inflow at the point. The curl of a vector field...
Divergence and Curl of a Vector: The divergence of a vector is given by: {eq}\displaystyle \nabla \cdot \vec{A} = (\frac{\partial}{\partial x} \hat{i} + \frac{\partial}{\partial y} \hat{i} + \frac{\partial...

Given F(x,y,z)=(xz)i+(y2z)j+(xz)k, find the divergence of F and the curl of F at P0(1,−1,2). Divergence and Curl of a Vector field: In vector calculus, Divergence of a vector field means the net flow or flux of the field through a g...
curl and divergence appear in mathematical descriptions of fluid mechanics, electromagnetism, and elasticity theory, which are important concepts in physics and engineering. We can also apply curl and divergence to other concepts we already explored. For example, under certain conditions, a vector field...

Curl and Divergence Operator: The curl of a vector field is defined as the cross product between the nabla or del operator and the vector field itself. On the other hand, the divergence of a vector field is the dot product of the del operator and the v...
