Download the latest version

Quickly set up high-resolution cross-shore wave transect models that run far faster than full 2D or 3D simulations. Ideal for long-term studies and detailed near-shore process analysis.

New! | 1D and 2DV Transect Wave Models

Wave generation for irregular waves now runs significantly faster, helping you complete large projects more efficiently.

Update | Faster Wave Model FM Calculations

New! | Quickly generate 3D surfaces from Supermesh elements:

&nbsp;
Two additional methods improve how flocculation is represented. A new empirical approach and an advanced physics-based solution deliver more accurate predictions of sediment transport and deposition.

New! | Flocculation of Cohesive Sediments

&nbsp;
A new function accounts for limited sediment availability, improving the realism of littoral drift simulations.

New! | Starving Bed Model in Littoral Processes FM

Supporting more realistic modelling of soft-engineered and nature-based solutions, you can now represent 2D and 3D porous structures, such as weirs or buildings, directly in hydrodynamic simulations.

New! | Porous Structures in the Flow Models

Updates include improved stability across culverts and weirs, new options for wave height input, floating gate structures, and more.

Update | Smaller Enhancements and Fixes
