Here I write a list of to-do things:
- Find a clever way to set the char array in header. Should be set in the config file and then probably use some getValue?
- Re-check velocity units
- How important is the EKIN parameter of the header to start ART. We are not calculating it. It could be done when writing the files but seems to much work taking into account that it is probably calculated at each timestep.
- astep parameter: clarification on how is set/chosen for the initial conditions. It is important for subsequent steps or ART auto-regulates the next steps?
- Need some clarifications for zoom-in simulations:
+ which NROWC and NGRIDC is used (now using levelmin, but levelmax?)
+ Number of files. Not clear if all together in one or one for each level (in the last case we will need to do some important changes in the module)
- Confirm our current format is standard for all ART versions.
also the 'LINGER++' one was present (they used the same class name, so which one
was actually used depended on the compile order rather than the user choice).
* Added new transfer function type 'music' which reads in a file with
density and velocity transfer functions for baryons and CDM.
* Powerspectrum evolution in two-fluid sim appears to scale as
predicted now at the per cent level
* Tool to compute velocity transfer functions is not included as of
now. Let's see..
* Velocity potentials are not yet supported with 2LPT.
Buffer block size can be set by [output]/gadget_blksize, default is 2**20=1048576 so that the
buffer contains 8*2**20 bytes for doubles = 8MB for one write/read operation
* Moved hybrid poisson solver from convolution_kernel.cc to poisson.cc
* Fine-tuned deconvolution schemes for various running modes
* Added lots of doxygen documentation
Note to myself: don't fix signs while listening to talks!!
Other mods/fixes:
* 2LPT is now supported also with distinct baryon/DM
power spectra. This creates now an overhead when
using Eisenstein&Hu or BBKS. But who cares.
* Reverted to determinant formulation of LLA rather than
second order expansion. This is much more accurate.
* Added baryon density filter. Baryon density field is now
consistent with CIC DM density. This is achieved by
convolving with an additional grid cell filter (and
no deconvolution).
* Tested LLA, skewness is now exact to a few per cent
but tends to be systematically higher.
* 2LPT needs a bit less memory now in multigrid mode
(FFT based 2LPT still needs humongous amounts).
* Cleaned up code output.
* The DM transfer function is now deconvolved with the cell assignment
function in order to restore power near the Nyquist wavenumber.
* Added an option to change the random number sample cube size
[random]/cubesize. This should be set >128 to generate un-
correlated numbers. True fix pending.
* Removed some unused code
* Increased Buffer size for Gadget-2 output plug-in
Fixed a bug with top grid kernel normalization, this reduces errors a bit.
A non-cubic grid is now extended to a cubic grid in the density calculation. This should reduce artefacts due to TF truncation.
Added a new (undocumented and internal) parameter that forces grid centering on the specified refinement region also in unigrid mode. This should in the future also obey that the shift comes in multiples of the top grid cells (which are however unknown).
Fixed a bug in the generic output plugin that caused non-cubic grids to be cut to cubic grids.
