hypnotoad
is available from the conda-forge
channel. Install with
$ conda install -c conda-forge hypnotoad
To use the GUI, one of PySide2 or PyQt5 is needed (PySide and PyQt4 may also work, but have not been tested). Install with
$ conda install -c conda-forge pyside2
or
$ conda install -c conda-forge pyqt
hypnotoad
can be installed using pip
by running
$ pip install --user hypnotoad
To use the GUI, one of PySide2 or PyQt5 is needed (PySide and PyQt4 may also work, but have not been tested). These can be fetched by choosing a variant. For PySide2 use
$ pip install --user hypnotoad[gui-pyside2]
or for PyQt5 use
$ pip install --user hypnotoad[gui-PyQt5]
If you need to modify the hypnotoad code, or get development versions, clone from github
$ git clone git@github.com:boutproject/hypnotoad.git
You can install from the git repo with pip
, this is useful to get the
executables added to your path. If you use conda
you may wish to first
install the dependencies using
$ conda install boututils matplotlib netcdf4 numpy optionsfactory pyqt pyyaml qt.py scipy
(replacing pyqt
with pyside2
if you prefer PySide2 to PyQt5) to ensure
they are not pip
-installed. Make sure to do an 'editable' install using
-e
or --editable
option like
$ cd hypnotoad
$ pip install --user -e .
(you may also need to pip
-install PySide2
or PyQt5
to use the GUI).
If installing in a conda environment you do not need the --user
argument.
This installs executables which use the code that's currently in the git repo,
so if you edit or update it you will see the updates. If you install with pip install .
(without the -e
) then pip
can get confused because it can't
tell which version number is newer, as the git repo versions have a version
number based on the git hash, not a simple x.y.z; then pip may for example not
uninstall hypnotoad correctly.
Note
A collection of tips about grid generation is kept on the wiki: https://github.com/boutproject/hypnotoad/wiki. Please add to it!
Options are read and set up in the Equilibrium (child-)class object, and passed from there to the Mesh (child-)class object.
User-settable options, with their current values, are printed when an Equilibrium object is created. Internal options should not need to be set by the user, but can be overridden with keyword arguments to the Equilibrium constructor.
Hypnotoad can be run either as an executable (hypnotoad-geqdsk
), which just
reads from an input file, using the gui (hypnotoad-gui
) or interactively
from a Python shell. To ensure reproducibility, it is suggested to create your
final grid non-interactively. The interactive mode is intended to make it
easier to prototype the grid and find a good set of input parameters. Once you
have found a configuration you are happy with, you can save the current input
parameters using the save dialog in the gui, or with
Equilibrium.saveOptions(filename='hypnotoad-options.yaml')
from the Python
shell; this may be especially useful if you have changed some options from the
Python shell with keyword-arguments.
Grid generation can take a while with the default options, which are set for high accuracy. When prototyping, it is suggested to temporarily use lower accuracy. The following may be a good starting point:
Hypnotoad provides several executables for working with equilibria and grid files:
hypnotoad-gui
is the main GUI interfacehypnotoad-geqdsk
is a command line interface for creating tokamak
equilibria from geqdsk equilibrium fileshypnotoad-circular
is a command line interface for creating grid files for
concentric, circular flux surfaceshypnotoad-torpex
is a command line interface for creating grid files for
TORPEX X-point configurationshypnotoad-plot-equilibrium
is a command line tool for creating plots of the
equilibrium (flux surfaces, wall and separatrix) from a geqdsk filehypnotoad-plot-grid-cells
creates a plot of the grid cells from a grid file
generated by hypnotoadhypnotoad-recreate-inputs
extracts from a grid file copies of the input
YAML file and geqdsk file that were used to create the grid file originallyFor more information, pass the --help
flag to any of these commands.
