Architecture Plus is an architectural modelling and analyses tool with too many modules. The term "plus" denotes for wind, solar and fire evacuation simulations. You can easily model basic architectural geometries and dynamic walls in 2D and 3D. Augmented reality (AR) based drawing mode makes the "3D modelling" process much more enjoyable with real shadows and particle tracking feature! 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 extra amazing features for you. 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. For instance, you can manipulate vertices of a basic cube to achieve more complex shapes.T he 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 colour in adaptation with speed. This app is developed for wind engineers, mechanical engineers and architects desire to solve fluid - solid interaction with Particle Based Simulation. The airflow around 3D geometries can be seen in high resolution thanks to faster convergence technics and innovative cell 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 changes 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! ---Features--- - 3D model import,view and analyse! - Architectural Modelling (Draw, erase and transform basic architectural geometries in either 2D mode or in 3D mode with Augmented Reality!) -Solar study (architects and urban planners) -Natural Ventilation Analysis (architects and engineers) -Building Aerodynamics Simulations (architects and engineers) -Urban Planning (architects, urban planners and engineers) -Fire Evacuation Module (Artificial Intelligence Based!) - Please note that it is at experimental stage, yet.
