Visualize real-time airflow with streamlines on the 3D geometry. This app is specially developed for wind engineers, mechanical engineers and architects to solve fluid - solid interaction with Navier - Stokes equations. With this app you can draw multiple geometries easily in 2D or 3D (Augmented Reality Mode) and can see the airflow around them 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. 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--- -Natural Ventilation Analysis (architects and engineers) -Building Aerodynamics Simulations (architects and engineers) -Urban Planning (architects, urban planners and engineers) - Draw and erase unlimited number of geometries in either 2D mode or in 3D mode (with Augmented Reality)! -Multiple storey buildings can be modelled and analysed. For analysis of different storeys, cut plane slider tool is developed.
