FDBB: Fluid Dynamics Building Blocks
FDBB - the Fluid Dynamics Building Blocks - is a fluid dynamics expression template library written in C++11 that provides the algorithmic building blocks for developing computational fluid dynamics (CFD) tools. It is designed as a header-only C++ library that can be easily integrated into existing CFD codes. FDBB is used in the compressible flow solver implemented in the G+Smo library.
FDBB is implemented as expression template library that builds on existing vector expression template libraries (ETL). The main features of the FDBB library are:
- unified API for variables, fluxes, and flux-Jacobians for arbitrary ETLs;
- use of full functionality and computational efficiency (OpenMP/MPI, CUDA, OpenCL, etc.) of the underlying ETLs;
- minimal computational overhead;
- easy integration of new ETLs.
