This is a NASA technical report on the software FUN3D
FUN3D is a suite of computational fluid dynamics (CFD) simulation and design tools developed by NASA Langley Research Center. It utilizes mixed-element unstructured grids and supports various grid formats, including structured multiblock and overset systems. The software includes capabilities for formal design optimization, error estimation, mesh adaptation, reacting flows, real-gas simulations, and GPU acceleration.
The document provides comprehensive instructions on installing the software and its optional dependent packages. It covers the execution of the flow solver and adjoint solver, grid generation and adaptation techniques, and the setup for design optimization tasks. Additionally, it details the use of Graphics Processing Units (GPUs) to accelerate solutions and describes the Stabilized Finite Elements (SFE) method.
FUN3D offers design optimization using adjoint solvers and various objective functions.
