Different discretizations of the gradient and curl operators are considered for a staggered grid in a height-based terrain-following coordinate system. A combination of discrete operators is identified that guarantees the mimetic property that the curl of the gradient of any scalar vanishes identically....

2. 旋度:在这里只作一个通俗而即为了保持面积元素还是正的, 我们必须对Jacobi 行列式(Jacobian) 取绝对值, 这里D′是同一公式表出来, 这个定理(或公式) 也叫做斯托克斯(Stokes) 定理(或Stokes 公式)梯度(gradient)、旋度(curl) 与散度(dive 3. 3. 卷曲:如覆膜(Laminating)、起膜(Delamination)、亏膜(short ...
When was the gradient operator was already defined? What does gradient operator have to do with curl? That definition of curl is senseable and standard, though other definitions are possible. Just because we write grad(something)=∇(something) and curl(something)=∇×(something) does not ...

[curlx,curly,curlz,cav] = curl(X,Y,Z,Fx,Fy,Fz) computes the numerical curl and angular velocity of a 3-D vector field with vector components Fx, Fy, and Fz. The output curlx, curly, and curlz represent the vector components of the curl, and cav represents the angular velocity of ...
The curl of a vector field is a measure of how much the vector field swirls. Mathematically, the curl of a vector field is the cross product of the gradient and a vector. How do you find the curl of a vector? To find the curl of a vector field, set up a 3x3 matrix where the ...
The curl of a vector can be determined by using the expression. Fx Fy Fz The curl of a given vector can be determined by taking the cross product of the gradient and the given vector. Answer and Explanation:1 Given Data The vector is; {eq}{\bf{F}}\le...
The central assumption here is a linear field variation (i.e. a linear gradient) between spacecraft so that J is constant over the spacecraft volume. Generally, this requires that the spacecraft separation is much less than the scale lengths on which the current density varies. If this ...
Given thatϕ(x,y,z)=x2y3−xz.Find the curl gradϕ. Question: ϕ(x,y,z)=x2y3−xz. ϕ Gradient of a Scalar Function: The gradient of a scalar function of three variables is a three-dimensional vector field. Each component of the gradient vector coincides with t...
