Abstract
A method for generating structured meshes from vector fields is described. The method is based on a weighted variational principle that minimizes a least-squares fit to the inverse Jacobian matrix. The weight is constructed from the vector fields by requiring local alignment of the mesh with the fields and by prescribing local length scales. The resulting grid generator is a weighted form of the Laplace grid generation equations. The method is demonstrated in 2D using a subsurface flow-field derived from hydrologic simulations.
