  The Indoor Geometry Generator (IGG) is able to generate automatically
simplified indoor geometry and its associated unstructured mesh for
Computational Fluid Dynamics (CFD) simulations purposes given very simple user
inputs. A large number of indoor features are supported by IGG such as
(non-exhaustive list): shelves, tills, tables, chairs, seats... Smaller
features such as laptops, computer towers and screens can also be included. In
addition, doors/windows as well as ventilation inlet and outlet can be taken
into account. Finally, the adding of simplified shape of humans standing,
sitting or lying are also supported by IGG. IGG allows the user to generate
without much effort indoor geometries such that shop, train, bus, plane,
school, open spaces..., while being fully consistent with CFD requirements. The
geometry and the mesh are outputted in GMSH format supported by both Fluidity
and IC-FERST open-source finite-element CFD software.
