VisualWind (jp.gr.java_conf.wind.visualwind) on Google Play
The app VisualWind is a simple simulator for 2D wind tunnel. It simulates the flow of air around objects of arbitrary shape placed in the wind. Air is treated as incompressible viscous fluid in the simulation. After drawing objects in [Geometry] in Menu, go to [Simulation]. You will see the flow developing with the passage of time for the default parameters. If necessary, it is possible to interactively correct the shape of objects and parameters at any time. Have fun.************************************************************************************ Note that this app is the same as the free version in terms of function,but it is about 40% more in the number of calculation points than the free version. More precisely, it depends on the screen resolution of your device.************************************************************************************
