Doctoral student Mohammad Zandsalimy and supervisor Dr. Carl Ollivier-Gooch have approached an ongoing problem in fluid simulation in their recent publication in the Journal of Computational Physics. Meshes are used to calculate complicated geometrical shapes, like topographies or computer graphics. Unstructured meshes are used to solve particularly complex problems like fluid flow, whereas structured meshes calculate quickly and accurately, but don’t represent as complex structures. With the complexity of unstructured meshes comes a give and take between the accuracy of the computations and the speed it takes the computer to execute them, as well as increased possibility for errors and instability. This paper presents a solution to the issue of stability, making unstructured meshes more reliable, accurate and faster to use in complex calculations.
