Divergence-free
Extracted from the Wikipedia article Solenoidal vector field.
In vector calculus and differential equations, a divergence free vector field is a vector fieldv with divergence zero at all points in the field: In electromagnetic theory, a divergence-free vector field is commonly called a solenoidal vector field, while in hydrodynamics it is commonly called an incompressible vector field, and in mathematical physics it is sometimes called an transverse vector field).
