PyNDI

PyNDI (NTU Damage Index calculator) provides a simulator-based calculator for damage index calculation.

Overview

The damage index calculated in this program is basically based on the FEDI (Fire and Explosion Damage Index). Firstly, hazadous chemicals will be defined in advance. Secondly, the program will search the and determine which unit may provide the most huge FEDI and let it represent the whole process. By these two steps, the operation iteration can be reduced. Finally, this progream connect with Aspen Plus for damage index evaluation.

Required Package

pip install -r requirements.txt

or intall through

pip install PyNDI
