Transport

class Transport(*args, **kwargs)

This class implements steady-state linear transport calculations.

Parameters:

The coefficient matrix, A (in Ax = b)

Np

Nt

Ps

Ts

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

params

project

settings

x

Shortcut to the solution currently stored on the algorithm.

Methods

clear_BCs([bctype])	Clear all BCs of the given type(s)
clear_rate_BCs()	Clears all rate BCs
clear_value_BCs()	Clears all value BCs.
filter_by_label([pores, throats, labels, mode])	Returns which of the supplied pores (or throats) has the specified label(s)
get_conduit_data(propname)	Fetches an Nt-by-3 array of the requested property
interpolate_data(propname[, mode])	Generates an array of the requested pore/throat data by interpolating the neighboring throat/pore data.

num_pores([labels, mode])	Returns the number of pores of the specified labels
num_throats([labels, mode])	Return the number of throats of the specified labels
pores([labels, mode, asmask])	Returns pore indicies where given labels exist, according to the logic specified by the mode argument.
props([element])	Retrieves a list of keys that contain numerical data (i.e.
rate([pores, throats, mode])	Calculates the net rate of material moving into a given set of pores or throats
run([solver, x0, verbose])	Builds the A and b matrices, and calls the solver specified in the settings attribute.

set_value_BC([pores, values, mode])	Applies constant value boundary conditons to the specified pores.
throats([labels, mode, asmask])	Returns throat locations where given labels exist, according to the logic specified by the mode argument.
to_indices(mask)	Converts a boolean mask to pore or throat indices
to_mask([pores, throats])	Generates a boolean mask with True values in the given locations
