Fluid Dynamics Simulation on a GPU

Abstract

We solve the Navier-Stokes equations for incompressible fluid flow onmodern GPU (Graphics Processing Unit) computing devices, using theDirectX11 API by Microsoft. We implement the well-known projectionmethod on DirectX compute shaders in the languages HLSL (High LevelShader Language) and C++. We compute the flow inside of a lid-drivencavity and compare results to those from the standard benchmark. Wealso discuss future developments to enable the use of open software standardsto achieve better results
