A minimal Python package that produces slice plots through h5m DAGMC geometry files

Installation

pip install dagmc_geometry_slice_plotter

Python API Usage

These examples assume you have a h5m file called dagmc.h5m in the same folder that the Python script is being run from.

Create a plot of a slice through the geometry perpendicular to the Z axis and default settings elsewhere. This will slice through the the center of the geometry as plane_origin has not been specified.

from dagmc_geometry_slice_plotter import plot_slice_of_dagmc_geometry

plot = plot_slice_of_dagmc_geometry(
    dagmc_file_or_trimesh_object='dagmc.h5m',
    plane_normal=[0, 0, 1],
)

plot.show()

Create a plot of a slice through the geometry perpendicular to the Z axis, offset by 200cm and with default settings elsewhere.

from dagmc_geometry_slice_plotter import plot_slice_of_dagmc_geometry

plot = plot_slice_of_dagmc_geometry(
    dagmc_file_or_trimesh_object='dagmc.h5m',
    plane_origin=[0, 0, 200],
    plane_normal=[0, 0, 1],
)

plot.show()

Create a plot of a slice through the geometry perpendicular to the Y axis, with a rotation of 45 degrees and with default settings elsewhere. Also saves the plot with a high resolution (DPI)

from dagmc_geometry_slice_plotter import plot_slice_of_dagmc_geometry

plot = plot_slice_of_dagmc_geometry(
    dagmc_file_or_trimesh_object='dagmc.h5m',
    plane_normal=[0, 1, 0],
    rotate_plot=45,
)

plot.savefig('my_plot3.png', dpi=600)

Saves a png image of a plot of a slice through the geometry perpendicular to the X axis and with default settings elsewhere.

from dagmc_geometry_slice_plotter import plot_slice_of_dagmc_geometry

plot_slice_of_dagmc_geometry(
    dagmc_file_or_trimesh_object='dagmc.h5m',
    plane_normal = [1, 0, 0],
    rotate_plot=270,
    output_filename='my_plot4.png'
)
