Hydrodyn-OILSOFT

It is an absolute user friendly system, developed specifically for environmental engineers, who may not have much exposure to numerical concepts in data creation , calculation and analysis.

What is OILSOFT?

Hydrodyn-OILSOFT is an advanced software package, with a Graphical User Interface(GUI) consisting of pre-processor, multiple solvers and post processor that can simulate fate and movement of oil spills, in rivers, seas and coastal waters of estuarine systems in a complex geometry with high precision using higher order numerical schemes. OILSOFT provides rapid predictions of the movement of spilled oil in all meteorological and hydrological conditions. It includes user friendly graphical interface for entering both wind and hydrological data and specifying the spill source scenario.

Hydrodyn-OILSOFT includes many specialized features of graphics and menu driven pre/postprocessor for setting up the input, running the calculation, and selecting and obtaining graphical output from the analysis, animation facilities, trajectory plots etc. It allows fast, flexible creation and modification of computational models to reduce the possibility of errors in the input. It is available for UNIX workstations and IBM compatible PC's under all MS Windows environment.

Features

• Uses a finite volume / finite difference approach.


• Built-in Grid Generator, which is based on BFC methodology.


• Interactive with GIS data management system.


• It can display the oil slick trajectory at any time during the computation.


• It is capable of handling various type of oils in the prediction of fate and trajectory of oil spills in open waters.


• Integrated Spill Trajectory and Fates model, Stochastic model, Backtracking model, Subsurface Transport model for sub-sea releases and blowouts in the program.


• Comprehensive oil characteristic database in built.


• Spill scenarios can be spoecified.


• Input winds time series feasible.


• Capabioity to enter and edit oil types in the oil library.


• Displays GIS resources affected by the oil trajec­tory.


• The GIS utility is highly interactive and allows the user to enter, or import from external GIS sources, a variety of geographic data such as response resources, environmentally sensitive areas, and key coastal features.


• It has animation facility for output results of various file formats i.e. Bitmap, ASCII.


• Dispersant effectiveness and over-flight update tools built-in.

Software Capablities

• This software is flexible and can be used for any geographical locations in the world.


• It can be used to simulate slick trajectories in tidal and non-tidal flow domains.


• The model can be used for either continuous or instantaneous oil spills and the model takes into consideration various processes including advection, mechanical spreading, horizontal turbulent diffusion, evaporation, dissolution and shoreline deposition.


• It allows fast, flexible creation and modification of computational models, while greatly reducing the possibility of errors in the input.


• It can be used either as a real-time basis to predict the movement of oil spill or as a scenario model to analyze the possible impact of accidental oil spill.
