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 NESSOFT?

Hydrodyn-NSESOFT an advanced computer program used to simulate propagation of Noise in the atmosphere under various meteorological conditions and complex topographical features. The software uses user defined or automatically generated computational grids for solving the basic governing equations of atmospheric flows and noise. It uses Finite Element Method to map the physical domain features to be modeled exactly and with generalized land boundaries.

NSESOFT is capable of predicting the noise levels due to single/multiple point or line type of noise sources. It takes into account the effect of barriers, buildings and vegetation on the propagation of noise. Ground absorption and meteorological effects like wind, humidity and temperature are also accounted for. Multiple sources at different frequencies can be easily handled.

NSESOFT includes many specialized features of graphics and menu driven pre/post -processor for setting up the input, running the calculation and selecting and obtaining graphical output from the analysis. It allows fast, flexible creation and modification of computational models, while greatly reducing the possibility of errors in the input. It is available for UNIX workstations and IBM compatible PC's under MS Windows 95 or Windows NTplatform.
