Easily model basic architectural geometries in 2D and 3D. Augmented reality based drawing mode make the modelling process much more enjoyable with real shadows. You may conduct shadow range analysis with specifying latitude and longitude and other parameters. Real-time airflow may be visualised with streamlines changing in size and color in adaptation with speed. This app is also 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. The unique 3D modelling algorithm works very fast and easy to get adapted. The Graphical User Interface is very easy to get which button makes what, besides the help screen is interactively shows button functions. Lastly, in wind engineering and architecture, you may use this app for building aerodynamics analyses since it has a unique robust 3D modelling system. This app make the user understand Computational Fluid Dynamics basics and nature of the wind in real-time with the virtual geometries caste on the real surfaces! ---Features--- - Draw,erase and manipulate unlimited number of 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) -Multiple storey buildings can be modelled and analysed. For analysis of different storeys, cut plane slider tool is developed.
