CFD data compression methods based on Full-3D and Quasi-1D supercompact multiwavelets are presented supercompact wavelets method provide advantageous benefit that it allows higher order accurate representation with compact support Therefore it avoids unnecessary interaction with remotely located data across singulanties such as shock. Full-3D wavelets entails appropriate cross-derivative scaling function & wavelets, hence it can allow highly accurate multi-spatial data representation Quasi-1D method adopt 1D multiresolution by alternating the directions rather than solving huge transformation matrix in Full-3D method. Hence efficient and relatively handy data processing can be conducted Several numerical tests show swift data processing as well as high data compression ratio for CFD simulation data.
