Below are files that can be manipulated or used as initial conditions, state.cdf.in. A Main.info should be provided with each state file containing parameter settings.
- Files may be loaded with with different parameter settings. If there is a change in resolution, data will be interpolated or truncated automatically.
- The state file contains spectral coefficients of the velocity perturbation. Each component has dimension (N,H,2), where N is the number of radial points, H is the number of Fourier coefficients, and 2 corresponds to real and imaginary parts. Indices [1,H] in the state file correspond to indices [0:H-1] in the code; see Core_implementation#Ordering_the_Fourier_modes.
- For visualisation, data needs converting to real space. See comments in the file matlab/Readme.txt supplied with the code.
Sample Initial Conditions
- Turbulence at Re=2400. L=2.5D (alpha=1.25) File:Re2400a1.25.tgz
- Turbulence at Re=2400 with m=2 symmetry. L=2.5D (alpha=1.25) File:Re2400m2a1.25.tgz
- Turbulence at Re=4500 in the '2+epsilon' model. L=10D File:Re4500.2eps.a0.314.tgz
- Turbulence at Re=5300. L=5D, Re_tau approx 150.
- Puff at Re=1900.
Relative Equilibria
- S1, S2...
- M1, M2...
- N1, N2...
