COMPUTATIONAL AERODYNAMICS
An efficient edge based data structure has been implemented within the HEMLAB solver for a three-dimensional vertex based finite volume algorithm in order to demonstrate its efficiency compared to the classical edge based implementations. In the present approach, the data structure is tailored to meet the requirements of the algorithm by considering the data access pattern and cache efficiency. The present data structure is not limited with tetrahedral elements, arbitrary polyhedral elements are also supported in the mesh without putting any additional effort.
