TUFLOW software development began in 1972 with the birth TUFLOW 1D (ESTRY). Like all TUFLOW products, ESTRY has continually evolved since its initial inception. TUFLOW 1D's numerical free-surface flow solution uses an explicit finite difference, 2nd order Runge-Kutta solution technique to solve the Saint Venant unsteady fluid flow equations and includes the inertia terms. In addition to the 1D free-surface flow equation TUFLOW 1D includes numerous structure equationss. These are:
* Culverts and pipes network (pressurized or non-pressurized)
* Pit, manholes and junctions within pipe networks
* Numerous weir equations
* Pumps and gates
* All of the above can be configured with "operation controls".
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. 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 upto 100 times compared to a single CPU. Please refer to the FAQ section below for a more extensive discription of the differentce between the different 2D SWE computational

TUFLOW Software includes two grid computational solver options, namely TUFLOW Classic and TUFLOW HPC. TUFLOW Classic uses a finite difference implicit solution. TUFLOW HPC uses a finite volume explicit solution. The fundamental differences between both computational methods are described in the FAQ section below. Functionally, model input and outputs from TUFLOW Classic and TUFLOW HPC use identical formats.
