Transport

class Transport(*args, **kwargs)

This class implements steady-state linear transport calculations.

Parameters:

network (dict) – An OpenPNM Network object, which is a subclass of a dict

Attributes:

A

The coefficient matrix, A (in Ax = b)

Np

Shortcut to retrieve the number of pores in the domain

Nt

Shortcut to retrieve the number of throats in the domain

Ps

Shortcut to retrieve the indices of all pores

Ts

Shortcut to retrieve the indices of all throats

b

The right-hand-side (RHS) vector, b (in Ax = b)

iterative_props

Finds and returns properties that need to be iterated while running the algorithm.

name

network

Shortcut to retrieve a handle to the network object associated with the

params

This attribute stores ‘scalar’ data that can be used by pore-scale models.

project

settings

x

Shortcut to the solution currently stored on the algorithm.
