Maelstrom

This is work in progress. Please bear with us, the app is buggy - many updates and interesting features to come.

With Maelstrom you watch and interact with flows simulated on your very phone or tablet. This is known as computational fluid dynamics (CFD) but Maelstrom does not require a super-computer - all it takes is your Android device! The simulation is carried out real-time, allowing you to stir the flow using the tip of your finger.

Instructions:

The app simulates fluid flow in the direction of gravitational acceleration; change the direction of the flow by tilting the device.

Model details:

Maelstrom is a realtime fluid flow simulator. It solve the vorticity formulation of the incompressible Navier-Stokes equations via a vortex particle method.

Time integration: Forward Euler.

Spatial approximations: Second order finite difference.

Iterative solver: Geometric multigrid.
