A tool to analyze results from idefix/pluto simulations (for protoplanetary disks more specifically)
Project description
nonos
nonos is a 2D visualization command line application for planet-disk hydro simulations, as well as a Python library. It works seamlessly with vtu-formatted data from Pluto, Fargo3D and Idefix.

Ongoing progress
- spherical coordinates
- error:
streamlines
&rz=True
-> not yet implemented - warning:
isPlanet=False
&corotate=True
-> we don't rotate the grid if there is no planet for now.omegagrid
= 0. - warning:
geometry="polar"
&rz=True
-> plot not optimized for now in the (R,z) plane in polar.
Installation
:warning: Nonos requires Python 3.8 or newer. The easiest installation method is
$ pip install nonos
Usage
1. On the command line
The nonos CLI gets its parameters from three sources:
- command line parameters
- a configuration file
- default values
Command line parameters take priority over the configuration file, which itself takes priority over default values.
To get help, run
$ nonos --help
usage: nonos [-h] [-dir DATADIR] [-field {RHO,VX1,VX2,VX3}] [-vmin VMIN]
[-vmax VMAX] [-cpu NCPU] [-on ON [ON ...] | -all] [-diff] [-log]
[-isp] [-corotate] [-grid] [-streamlines] [-rz] [-noavr] [-pbar]
[-stype {random,fixed,lic}] [-srmin RMINSTREAM]
[-srmax RMAXSTREAM] [-sn NSTREAMLINES]
[-geom {cartesian,polar} | -pol] [-dim {1,2}] [-ft FONTSIZE]
[-cmap CMAP] [-fmt FORMAT] [-dpi DPI] [-input INPUT | -isolated]
[-d | -version | -logo | -config]
Analysis tool for idefix/pluto/fargo3d simulations (in polar coordinates).
optional arguments:
-h, --help show this help message and exit
-dir DATADIR location of output files and param files (default:
'.').
-field {RHO,VX1,VX2,VX3}
name of field to plot (default: 'RHO').
-vmin VMIN min value in -diff mode (default: -0.5)
-vmax VMAX max value in -diff mode (default: -0.5)
-cpu NCPU, -ncpu NCPU
number of parallel processes (default: 1).
-on ON [ON ...] output number(s) (on) to plot. This can be a single
value or a range (start, end, [step]) where both ends
are inclusive. (default: last output available).
-all save an image for every available snapshot (this will
force show=False).
-geom {cartesian,polar}
-pol shortcut for -geom=polar
-dim {1,2} dimensionality in projection: 1 for a line plot, 2
(default) for a map.
-ft FONTSIZE fontsize in the graph (default: 11).
-cmap CMAP choice of colormap for the -dim 2 maps (default:
'RdYlBu_r').
-fmt FORMAT, -format FORMAT
select output image file format (default: unset)
-dpi DPI image file resolution (default: DEFAULTS['dpi'])
boolean flags:
-diff plot the relative perturbation of the field f, i.e.
(f-f0)/f0.
-log plot the log10 of the field f, i.e. log(f).
-isp is there a planet in the grid ?
-corotate does the grid corotate? Works in pair with -isp.
-grid show the computational grid.
-streamlines plot streamlines.
-rz 2D plot in the (R-z) plane (default: represent the
midplane).
-noavr, -noaverage do not perform averaging along the third dimension.
-pbar display a progress bar
streamlines options:
-stype {random,fixed,lic}, -streamtype {random,fixed,lic}
streamlines method (default: 'unset')
-srmin RMINSTREAM minimum radius for streamlines computation (default:
0.7).
-srmax RMAXSTREAM maximum radius for streamlines computation (default:
1.3).
-sn NSTREAMLINES number of streamlines (default: 50).
CLI-only options:
-input INPUT, -i INPUT
specify a configuration file.
-isolated ignore any existing 'nonos.toml' file.
-d, -display open a graphic window with the plot (only works with a
single image)
-version, --version show raw version number and exit
-logo show Nonos logo with version number, and exit.
-config show configuration and exit.
Using a configuration file
The CLI will read parameters from a local file named nonos.toml
if it exists,
or any other name specified using the -i/-input
parameter.
To ignore any existing nonos.toml
file, use the -isolated
flag.
One way to configure nonos is to use
$ nonos -config
which prints the current configuration to stdout. You can then redirect it to get a working configuration file as
$ nonos -config > nonos.toml
This method can also be used to store a complete configuration file from command line arguments:
$ nonos -ncpu 8 -cmap viridis -rz -diff -vmin=-10 -vmax=+100 -config
As of Nonos 0.2.0, this will print
# Generated with nonos 0.2.0
datadir = "."
field = "RHO"
dimensionality = 2
on = "unset"
diff = true
log = false
vmin = -10.0
vmax = 100.0
rz = true
noaverage = false
streamtype = "unset"
rminStream = 0.7
rmaxStream = 1.3
nstreamlines = 50
progressBar = false
grid = false
geometry = "cartesian"
isPlanet = false
corotate = false
ncpu = 8
fontsize = 11
cmap = "viridis"
dpi = 200
2. Programmatic usage
We are still working on nonos' api.
