configure.py options

• Must enable
  • --model=ELBDM
• Must disable
  • --gravity
  • --particle
• Available options
  • Miscellaneous Options

Default setup

• Evolve vortex pair for one period
• Use the periodic boundary conditions
• Wavelengths along x and y can be adjusted to multiples of the box size
• Wave in z-direction is turned off by default

Note

• Evolve vortex pair with linear motion along x in a 2D simulation
  • Wave function psi_vorpair(x,y) = background + A*cos(ky*y)*exp( i*(kx*x-Omega*t+Phase0) ) where A is a constant on the order of background, kx and ky are wavenumbers, Omega=0.5/ELBDM_ETA*(kx^2+ky^2), and Phase0 is a phase constant
• Optionally: Add wave in z direction
  • psi(x, y, z) = psi_vorpair(x,y) + background_z * exp( i*(kz*z-ZWaveOmega*t) ) where background_z is a constant on the order of background, kz is a wavenumber and Omega=0.5/ELBDM_ETA*(kz^2)
