ABSTRACT
<p><it>Abstract</it>—Particle path computation in unsteady 3D vector fields given in discrete, structured form (i.e., as a hexahedral curvilinear grid) requires the local approximation of the vector field and the path. Quadrilinear interpolation and Bernstein-Bézier polynomials are used for the local vector field and path approximation. The next point in a sequence of points on a particle path is computed using this local approximation. Bernstein-Bézier polynomials are primarily used in geometric modeling, and their properties allow direct computation of points on a particle path.</p>
INDEX TERMS
