TUFLOW General Discussion: Difference between revisions

[https://www.tuflow.com/products/tuflow/ TUFLOW’s 2D Fixed Grid Engines] are dynamically linked to TUFLOW 1D. There are two 2D grid computational solver options, namely TUFLOW Classic and TUFLOW HPC. Both provide second order depth averaged 2D solutions to the shallow water equations (SWE). TUFLOW Classic development began in 1989. It uses a finite difference implicit solution, and is the recommended tool for single core CPU compute. TUFLOW HPC development began in 2010. It uses a finite volume explicit solution. TUFLOW HPC is the recommended tool for GPU compute hardware, where code parallelisation across 1000's of GPU CUDA cores can achieve simulation speed increases of up to 100 times compared to a single CPU. Functionally model input and outputs from TUFLOW Classic and TUFLOW HPC use identical formats. Both solvers arehave a strong industry leaderreputation as leaders in simulation software for flood, catchment, integrated urban drainage and stormwater modelling applications.
