solenoidal

GVF model derives from generalized force balance equations, a vector diffusion equation is employed to diffuse the gradient of an edge map in regions distant from the boundary, yielding a general type of force field which can be decomposed into an irrotational component and a solenoidal component.

梯度矢量流（GVF）模型是从广义力平衡方程出发，利用能量最小公式，应用扩散方程扩散了边界区域的边缘映射梯度，产生了一种广义矢量场，包含无旋分量和无散分量。

From the expressions of the components of the displacement of such a. solenoidal wave, together with the boundary conditions at the surface with vacuum outside, it can be proved that the transverse wave cannot glide along the surface of that solid.
