Big Fluid and Particle Simulator

At the moment, this code is meant to run pseudospectral DNS of Navier-Stokes, using FFTW 3, and to integrate particle trajectories in the resulting fields. I'm trying to write it as general as possible, so that it can be expanded in the future; it remains to be seen how well this will work.

The Navier-Stokes solver has been extensively tested (tests are included in the repository), and it is working as expected. Parameters and statistics are stored in HDF5 format, together with code information, so simulation data should be "future proof".

Comments

  • particles: initialization of multistep solvers is done with lower order methods, so don't be surprised if direct convergence tests fail.

TODO

  • add different numerical method, for testing purposes
  • test involving hydrodynamic similarity
  • test anisotropic grids
  • test non-cubic domains
  • use HDF5 io for fields
  • try to make code more memory efficient
  • make code py3 compatible
