New Nord2000 calculation engine

Status: Closed - part of windPRO 3.1 Service Pack 2

Fixed in build: 613

The calculation engine for Nord 2000 calculations have been updated. (minor differences in the results must be expected)

Nord2000/Compro 2017'

This update contains performance improvements as well as bug fixes. The bugfixes include correction of the Nord2000 sound propagation method as well as correction of the implementation. The corrections have mainly to do with how Nord2000 handles screens and how this was implemented, particularly in situations where the meteorology creates an acoustical “shadow zone”, i.e. in some situations when there is a wind component from the receiver to the sound source.
