simple 2D airflow simulator
The app Wind Simulator II is a 2D wind simulator on mobile.The airflow around obstacles of almost all shapes drawn on the grid sheet can be simulated, if even a path of the air flow is secured. Air is treated as incompressible viscous fluid in the simulation.
Operation is easy: after drawing objects including boundaries in [Geometry] in Menu, go immediately to [Simulation].
You will see the flow developing for the default parameters with the progress of time.
If necessary, it is possible to interactively change the shape of objects and parameters at any time. Have fun.
