MESH GENERATION USING VECTOR-FIELDS

A method for generating structured meshes from vector fields is descri bed, The method is based on a weighted variational principle that mini mizes a least-squares fit to the inverse Jacobian matrix, The weight i s constructed from the vector fields by requiring local alignment of t he mesh with the fields and by prescribing local length scales. The re sulting grid generator is a weighted form of the Laplace grid generati on equations. The method is demonstrated in 2D using a subsurface flow -field derived from hydrologic simulations.
