Pretty nice So many different calculators and conversion stuff. Would be nice if some of these could be combined in one calculator. For example, I bought it for the electrical calculators. The current, power, resistance, and voltage calculator could easily be combined in one like the stand alone ones on the play store instead of having to open each one individually. Overall, a useful app

Turn your device into a wind tunnel simulator !
Draw obstacles and watch the fluid flow around. Experiment with different sizes, shapes, aerodynamic profiles and see what happens !

Visualize airflow with smoke, particles, or observe pressure field, velocity. The simulation engine also computes an approximation of lift and drag.

Visualize airflow with smoke, particles, or observe pressure field, velocity. The simulation engine also computes an approximation of lift and drag.

The Wind Tunnel free app lets you play with the fluid and understand physics effects.
Fluid motion is computed by solving Navier-Stokes equations, at high definition and in real-time thanks to optimized code taking the most out of CPU and GPU performance.

Observe the mechanism of lift/drag over an airfoil, and how it stalls when the angle of attack increases (use two-finger rotate gesture to rotate the scene).

This demo version includes 3 pre-defined scenes: airfoil, rocks or torus.

Choose between different visualization modes : Smoke, pressure or speed, and adjust input speed/ fluid viscosity.

In the "torus" mode you can draw/erase your own obstacles, the fluid wraps around the screen.

Use the android "back" or "menu" buttons to show/hide the interface.

## 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.
