✦ Synopsis

This paper presents a 3D mesh-aligning algorithm for convection-dominated convection-diffusion problems. The main difference between this algorithm and the 2D edge-swapping algorithms is that instead of swapping faces it splits the adjacent tetrahedra to obtain a more flowaligned mesh, and thereby, increase solution accuracy without increasing the number of meshpoints.

This paper proposes and studies an algorithm for aligning a triangulation with a given convection ΓΏeld. Approximate solutions of convection-dominated problems on ow-aligned meshes typically have sharper internal layers, less over and undershooting and higher accuracy. The algorithm we present can be

A unified approach for solving convection-diffusion problems using the Generalized Integral Transform Technique (GITT) was advanced and coined as the UNIT (UNified Integral Transforms) algorithm, as implied by the acronym. The unified manner through which problems are tackled in the UNIT framework a
