RiverFlow2D GPU is our lighting-fast model that achieves simulation speeds never seen before in 2D simulations. It allowing tackle high resolution or large river reach hydraulic problems that used to be impractical or even impossible until recently.
The release of the GPU version of RiverFlow2D flexible mesh model has been a game-changer for many 2D modelers that often find 600X faster simulations compared to non-parallelized or poorly parallelized models.
Traditional CPU processor performance has reached its peak, but Hydronia’s RiverFlow2D GPU developed in collaboration with the world-reknown Computational Hydraulics Group of the University of Zaragoza in Spain, offers a high performance numerical engine, that when run used with off-the-shelf NVIDIA graphics cards provides unsurpassed performance to the most demanding flooding simulations.
What can you simulate with RiverFlow2D?
Extremely detailed riverine and estuary hydrodynamics
River and floodplain interaction
Hydraulic impact of bridges and other hydraulic structures
Dam and levee break flooding
Very large river reaches

Hydronia recommends using one of the following graphics cards to run RiverFlow2D Plus GPU
NVIDIA GTX 1080 Ti for desktops
NVIDIA Tesla K40 and K80, P100
Note that the performance will highly depend on the card installed. Older generation NVIDIA cards may not allow the model to work properly. Use only one of the recommended cards above.
Hydronia has tested RiverFlow2D GPU in the above Tesla cards that offer the highest performance gain so far in the order of 200x depending on the mesh size.
