openpnm_to_im(network, pore_shape='sphere', throat_shape='cylinder', max_dim=None, rtol=0.1)¶
Generates voxel image from an OpenPNM network object.
network (OpenPNM GenericNetwork) – Network from which voxel image is to be generated
pore_shape (str) – Shape of pores in the network, valid choices are “sphere”, “cube”
throat_shape (str) – Shape of throats in the network, valid choices are “cylinder”, “cuboid”
max_dim (int) – Number of voxels in the largest dimension of the network
rtol (float) – Stopping criteria for finding the smallest voxel image such that further increasing the number of voxels in each dimension by 25% would improve the predicted porosity of the image by less that
im – Voxelated image corresponding to the given pore network model
- Return type
(1) The generated voxelated image is labeled with 0s, 1s and 2s signifying solid phase, pores, and throats respectively.
(2) If max_dim is not provided, the method calculates it such that the further increasing it doesn’t change porosity by much.
