37.1. Introduction to the Fluent GPU Solver

The Fluent GPU solver is a native GPU-powered Ansys Fluent solver, which uses the high performance of graphics processing units (GPUs) to facilitate the computation of complex simulations. The Fluent GPU solver can be used with one or multiple GPUs which is specified in the Fluent Launcher or the command line. Unlike CPUs, GPUs are optimized for parallel processing and have high bandwith memory, making them ideal for calculating computationally intensive flow solutions. This increase in performance of the GPU-powered solver has shown to increase the speed of flow calculations by up to 5 times that of traditional multi-core CPU-based computations.
