FAQ
What is iTurbo used for?
iTurbo performs a Direct Numerical Simulation (DNS) to solve the Navier-Stokes equations for two-dimensional incompressible homogeneous turbulence. It's designed for simulating complex fluid dynamics scenarios.
How does iTurbo simulate turbulence?
It solves the Navier-Stokes equations using a simple Euler method for time stepping and performs calculations in Fourier space for efficiency. The simulation involves transforming the vorticity field between normal and Fourier spaces.
What is the CFL number requirement for iTurbo?
The time step in iTurbo is calculated to ensure the CFL number does not exceed a given value. If the CFL number is greater than 0.8, the simulation will likely fail.
What devices does iTurbo support?
iTurbo is available on iPhone and iPod devices. It is designed for iOS platforms.
What is the age rating for iTurbo?
iTurbo has an age rating of 4+, making it suitable for a wide range of users interested in scientific simulations.
