[Bldg-sim] ArchPLUS

[Ilker Karadag]

Hi,

I would like to inform you that I have developed a mobile software for 3D
modelling, wind-building interaction analyses and solar study (shadow
range). Wind-building interaction anaylses is based on Navier Stokes
equations which is solved on distinct particles. Actually, a flow of
particles emitted from a source like in the wind tunnel, then these
particles interact with each-other and the solid surfaces based on the
equations.

ArchPLUS (Architecture Plus) is an architectural modelling and analyses
tool with too many modules. The term "plus" denotes for wind, solar and
fire evacuation (AI based) simulations.

You may easily model basic architectural geometries in 2D and 3D. Augmented
reality (AR) based drawing mode makes the "3D modelling" process much more
enjoyable with real shadows and real physics. It is possible to import any
3D model (*.obj) to this app and then run all of the simulations.

This app can be even used solely to view 3D models in your mobile phone in
2D and 3D AR environment. However, ArchPlus has a bunch of extra features.
You may conduct wind analyses, and also "Solar Study" with specifying
latitude, longitude and other parameters. Moreover, it is also possible to
conduct "Fire Evacuation Simulations" based on AI (artificial intelligence).

The unique 3D modelling algorithm works very fast and easy to be get
adapted. The Graphical User Interface is very easy to get which button
makes what, besides the help screen is interactively shows button functions.

Real-time airflow can be visualised with streamlines changing in size and
color in adaptation with speed. This app is developed for wind engineers,
mechanical engineers and architects desire to solve fluid - solid
interaction with Navier - Stokes equations. The airflow around 3D
geometries can be seen in high resolution thanks to faster convergence
technics and cutcell mesh type. Multiple storey buildings can be modelled
and analysed. For analysis of different storeys, cut plane slider tool is
developed to move wind tunnel analysis plane. This tool change the wind
tunnel plane to horizontal or vertical, as well. In brief, this app make
the user understand Computational Fluid Dynamics basics and nature of the
wind in real-time with the virtual geometries cast on the real surfaces.
