Abstract
This paper presents specific procedures for locally refining nodal connectivity of two-dimensional unstructured triangular meshes to improve the quality of the mesh as well as to increase solution accuracy and computational speed. Details of the procedure are outlined along with a discussion of similar work, and an example problem from hydrodynamics is shown.
