aha, no you're right nothing else needs to happen as far as I know - I'm used to gasoline and some habits die hard... ;) On Fri, 2011-08-05 at 11:39 -0400, Matthew Turk wrote:
Hi Rok,
Ah, my fault on that. I've swapped back; please verify if you could. The conversion factors for density and length and velocity are all grabbed from the info*.txt file; does an additional conversion step need to be applied?

thanks for the fix! works better now.
Another issue - unless I'm somehow reading this wrong - is that the redshift is interpreted incorrectly (or rather, it appears that redshift and expansion factor have been swapped):
yt : [INFO ] 2011-08-05 17:17:14,961 Parameters: current_redshift = 0.499963102849
but:
pn.parameters['aexp'] 1.00014759949511
this will probably mess up unit conversions, I would imagine.
best,
rok

Hi Rok,
I've pushed a fix to the tip for this; however, even after running a couple test problems in RAMSES, I was unable to determine how to definitively identify cosmological simulations from non-cosmological simulations. I've therefore set this parameter to always be on.
Please note that there are still issues with the RAMSES reader, and it may behave unexpectedly. Sam Geen, Oliver Hahn and I have been working on them, but it has been a bit slow going the last little while. If you have any specific suggestions or ways we could improve, we would definitely be interested in hearing them.
Thanks very much,
Matt

trying to read a RAMSES output from a cosmological zoom simulation, I get the following perplexing error:

this clearly is a cosmological simulation with the relevant parameters specified in the info*.txt file - is something else needed?
Thanks,
Rok
