Graphics Processing Units’ Accelerated Navier-Stokes Solvers for Unstructured Meshes: A Literature Review

Recent advances in graphics processing units (GPUs) computational hardware have provided opportunities to develop large-scale numerical models with complex geometric configurations at reduced run time for wide-ranging applications, including computational fluid dynamics. However, utilizing the GPU hardware at its maximum capacity remains challenging. There is a need to develop numerical solution algorithms to alleviate the above-mentioned bottleneck. This study reviews recent developments in GPU-based numerical solution algorithms for incompressible Navier-Stokes equations and unstructured meshes. This literature review aims to promote the creation and development of robust large-scale complex geometry numerical models with applications, including but not limited to computational fluid dynamics.
