a simple simulator for 2D wind tunnel
This app is a simple simulator on mobile for 2D wind tunnel. The flow around obstacles of almost all shapes drawn on the grid sheet can be simulated, if even a path of the wind is secured. 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 change the shape of objects and parameters at any time. Have fun.
