A MEMORY‐EFFICIENT UNSTRUCTURED GRID REFINEMENT ALGORITHM FOR COMPUTATION OF 3D STEADY VISCOUS FLOWS
Alexander I. Zhmakin · Communications in Numerical Methods in Engineering · 1997
An algorithm for local refinement of unstructured grids for computation of 3D steady viscous flows 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 refinement 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 flow regimes in a horizontal epitaxial reactor. © 1997 by John Wiley & Sons, Ltd.
