Constrained transport
Webtransport which we call constrained optimal transport. In this problem, the set of primal measures are further constrained by specifying their actions on a finite dimensional … WebMAC method [8] and its successors are of this type, and in MHD the constrained transport ... It is not often a constraint that the curl vanishes, and when it is, a potential formulation can be employed. However, in fluid dynamics, espe-cially in three dimensions (3D), the vorticity (which is defined as the curl of the velocity
