CubicTemplate

class openpnm.network.CubicTemplate(*args, **kwargs)

Simple cubic lattice with arbitrary domain shape specified by a template image

The class creates a standard Cubic network the same shape as the provided image, then trims pores from the network that are not in the mask.

Parameters

• template (array_like) – The array (image) describing the desired shape of the domain. All locations in the image that are marked as True are kept while the rest of trimmed to yeild the shape.

• spacing (array_like, optional) – The spacing between pore centers in each direction. If not given, then [1, 1, 1] is assumed.

• name (str) – An optional name for the object to help identify it. If not given, one will be generated.

Notes

The other arguments are the same as Cubic except that shape is inferred from the template image.

Examples

import openpnm as op
import matplotlib.pyplot as plt

im = op.topotools.template_cylinder_annulus(10, 15, 10)
pn = op.network.CubicTemplate(template=im)

# It can be plotted for quick visualization using
fig, ax = plt.subplots(figsize=(5, 5))
op.topotools.plot_connections(network=pn, ax=ax, linewidth=0.5)

plt.show()

For larger networks and more control over presentation use Paraview.
