✦ Synopsis

An algorithm for local re®nement of unstructured grids for computation of 3D steady viscous ¯ows 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 reconstruction. Additional savings in memory result from the fact that only grid re®nement is allowed. The method requires about 20 integer words of storage per tetrahedron. The performance of the algorithm is illustrated by computation of several non-isothermal ¯ow regimes in a horizontal epitaxial reactor.
