2c8023c1f2 Most of the stuff needed to produce initial conditions for Nyx. 
Still a little fragile...

d9fbe83bbc added new parameter [setup]/ref_dims=NX,NY,NZ to explicitly specify the resoluti 
on of the high resolution region.
added output of comoving size of high-res region to screen
added output of densest point also when using the generic output plugin

8ccd7c7dfe Implemented baryon output for ART module. Still under testing. 
Done some cleaning and commenting in all the ART module code.

f45bed11a9 Dark matter only art module tested and working ok. Units checked and ok. 
All previous questions solved.
Still waiting for one last zoom test (moderate resolution 512^3) to compare it with
gadget results but full box and low res zoom look ok.

We should start thinking in the baryon format output.

8040f40104 Gadget-2 plugin: added new parameters for length and mass units, allowed gadget coarse particle type to be specified in parameter file. Fixed bug that H0 instead of h was written to Gadget header. 2012-08-19 13:38:49 -07:00

ab24981135 - Fixed velocity units conversion. Still final test needed. 
- Header ascii variable can be set in the config file.
- astep variable for ART has to be given in the config file.

c7e6cd5825 ART module for dm-only operative. Right now the module generates all the files necessary with the correct format and (re-check mandatory) units. Therefore, ICs generated should run! 
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.

e6137dcf07 Fixed a bug that prevented the 'MUSIC' transfer function plugin to be used when 
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).

29822726ec Removed option "shift_back" for Gadget2 output as it can cause problems with zoom sims overlapping the periodic boundaries. 2011-08-29 14:00:47 -07:00
