@jgostick and @ma-sadeghi.. Dear professors I am getting a 0 value of rate while I saw in the examples that it has some value.. could you please tell me what this tells and is this value that I am getting is correct or not...?

[jgostick]

Hi @JahanzebTariq, are referring to the "0 / 55890" as a the rate being 0? This tells you the number of pores in which you have applied a rate boundary condition. The rate is found using the alg.rate() method.

@jgostick sir please guide a little more about this rate boundary condition please.. are my conditions correct and does this rate stands for the velocity boundary condition.. and what about the value boundary condition..

Here is a detailed tutorial on the process of how openpnm solves the system of equations: https://openpnm.org/examples/reference/simulations/basic_transport.html

Here is an example of find the rate of transport across the domain: https://openpnm.org/examples/applications/absolute_permeability.html

and here is an example that applies both rate and value boundary conditions at the same time (to different pores):
