Thank you very much Corentin for your help. The result we see are supposed to be after 10 steps of simulations, according to nml file. I've not created it and I think I don't perfectly understand how to build one. Would you have an example to start from and modify, so I could run my first "good" simulations and create my first Yt graphs? On 20 March 2018 at 10:33, Corentin CADIOU <contact@cphyc.me> wrote:
Hi Matthieu,
The reason you're seeing what you see is because the density field is uniform, so what you're seeing is basically a map of a constant field ± machine precision. I guess that after one timestep, this should look better.
On a side note, since you're doing a Sedov explosion, the density/temperature is not uniform on the grid. Maybe a quick test you could do is plot the temperature instead and see if you get something consistent. FYI, your minimum temperature is extremely low (1.2e-13K) so it may lead to a crash of RAMSES.
Also be careful that the default namelist found in some versions of ramses sets the explosion in one of the corner of the simulation, so if you do a naive slice centered on the center of the box, you'll see nothing.
Cheers,
Corentin

Hello everyone!
I'm simulating supernovae explosions with Ramses. I'm at the very very beginning of it. My first runs give nothing, but I'm unsure whether it's because I've misused Ramses or because I don't use YT properly to see results.
My config file is this one: https://expirebox.com/download/ 59d92f446fea392dc9a6189603f1dc34.html Result files are here: https://expirebox.com/download/ 6bd562f210199b6b8581525c84d86eff.html
When I try slices or projections, all I can see is that: https://ibb.co/jbeg9c
I've loaded it with import yt ds = yt.load("my_path/output_00001/info_00001.txt")
And then, tried things like yt.SlicePlot(ds, 'x', "density") or yt.ProjectionPlot(ds,'x','Density') (I've tried other axis too), but I can't get anything else that the image I've showed.
Could someone help me to determine if the problem comes from my basic first simulation (Sedov supernovae phase) or from my Yt plots? I would really appreciate some help!
Thank you very much
