Developed for almost 40 years, our 1D solver has become one of the fastest and most robust solutions available, making it an ideal choice for flood modelling applications.

1D Steady State Solver

The steady state solver provides both direct steady-state and Pseudo-Timestepping methods to optimise run-time and enhance model stability. The main steady state solution method is called the Direct Method and is applicable to in-bank flow regimes.

It is a fast and very accurate solution method which requires very little initial data. It also incorporates an optional accurate supercritical and transcritical flow solver which has the capability of modelling hydraulic jumps and supercritical flow to a high degree of accuracy.

The Pseudo-Timestepping method uses a Preissmann 4-point scheme and is often used to develop initial conditions for unsteady runs or where flows are initially out of bank.

Although easy to apply to simple systems, the steady state solver includes a full range of hydraulic structures and is able to model complex looped channels and transcritical flows in steep rivers. This gives our software a much wider range of application when compared to other steady state modelling software.
