Thanks, Rob. I've recreated the problem here, and it appears in our development version as well. I'll let you know when I've found a fix. There is clearly ...
We are looking at ionization fractions in primordial gas at low densities (n_H ~ 1e-5 but that isn't very important) with effectively no radiation background....
... i got identical ionizations with and without charge transfer for a primordial cloud irradiated by a STE blackbody at 12,000K. please post an example of...
... We have effectively no radiation background so the ionization is primarily collisional and we fix the temperature at the given value. We find this result...
... effectively ... the code includes a large chemistry network. the reactions that are responsible for the He ionization are described in Lepp et al. J Phys ...
I am running a grid of models with the new Kurucz models and a range of ionizing fluxes: hden 4 abundances _ism punch continuum "k350c.con" units microns ...
Good Day, all, I think I've come across something that Cloudy allows the user to do, but perhaps shouldn't (?): the "punch lines emissivity" allows one to...

Hi, The only thing you can do here is write your own routine GrnVryDpth(). A stub is located at the end of the file grains.cpp. With this you can define a...
Hi, I was wondering how high a priority this is. Quite a few of my numbers are off when using the grid command. If its not very high on the todo list, then...
Hi Rob, This is a long standing problem in the code. Optimizer runs suffer from the same problem. After each model the code needs to be returned to exactly the...
You might consider bringing the grain material out into the gas phase when they reach the sublimation point. There are options to vary the gas-phase abundance...
Hi there, this message had been moved into my spam folder - sorry for missing it. You could do a clumped medium - but clumps don't form in a 1D outflow. You...
... Dear Gary, Thanks for the reference. The Lepp et al. and Stancil et al. papers refer extensively to H+ + He -> HeH+ but do not explicitly list associated...
Hi James, thanks for the persistence! it is a bug. There is a recombination rate that was entered into the wrong array as an ionization process. The fix is...

Hi, I have a simulation "!The model has modest optical depth to electron scattering; tau=0.25". I want to know if the total optical depth in the mtable...
Hi there, Interesting point. The basic problem is, as you say, that the attenuated incident continuum is part of the quantity that goes into the continuum...
I used version 07.02.01 (and 07.02.00) of Cloudy with the input given below and the program stopped because of a floating point exception. If I remove either...
Hi Kilian, Thanks for bringing this to our attention! I have been able to reproduce the problem. The fix is quite straightforward. In Cloudy 07.02.01 take the...
... Hi there, line and continuum optical depths are kept separate. Line optical depths scatter the photon within the line and excite the upper level. Coherent...
Hi there, I've been playing around with the 'No Induced Processes' command. I've uploaded a plot showing cooling vs. temperature, and it shows that there is an...
Hi there, that command does many things, but most likely the process affecting what you are doing is UTA ionization. try replacing the "no induced" with "no...
Hi Gary, I'd vote for keeping the output of continuum-band emissivity (without the transmitted continuum component). For my particular application (modelling...

Hi, I am trying to make heating and cooling rates grid with different temperatures(T), densities, metallicities and redshifts, using a modified code from...
Hi, This is a known problem that will be fixed in the next release. The program runs out of file descriptors. If you include the statement: fclose( ioFILE ); ...
Thanks a lot, Peter, for your prompt and nice sugestion! It works beautifully after the change, and now I can make a big grid. Thanks a lot again. Daisuke ... ...
