Hydro-environmental modelling and analysis tool (HEMAT), a GUI based 2DH hydrodynamic and contaminant transport model on unstructured triangular grids

摘要

In this paper a GUI based 2DH hydrodynamic model will be introduced. The model works on unstructured triangular grids which is generated by one of it's own utilities namely MeshGenerator. The numerical part of the model employed some high resolution Godonov-type of scheme being high accurate and free of oscillation. Along with a brief introduction to the numerical engine of the model, the utilities of the model which have been designed to let the user supplying the required data accurately and easily, will be explained.
