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.
