In the multi-dimensional numerical simulation of certain multi-phase fluid flow processes, many phenomena are sufficiently localized and transient that self-adaptive local grid refinement techniques are necessary to resolve the local physical behaviour. For large-scale simulation problems, efficienc

Confident adaptive algorithms are described, evaluated, and compared with other algorithms that implement the estimation of motion. A Galerkin finite element adaptive approach is described for computing optical flow, which uses an adaptive triangular mesh in which the resolution increases where moti

An algorithm for local reยฎnement of unstructured grids for computation of 3D steady viscous ยฏows is proposed. It is based on strict conventions for grid elements numbering that allows one to reduce memory requirements and to minimize the increase in the execution time for grid structure reconstructi
