Porous Media Simulator using the Finite Element Method

🚧 Work in progress...

Introduction
Installation
Setting Cargo.toml
Examples

Introduction

This code implements simulator using the finite element method for the behavior of solids, structures, and porous media.

See the documentation for further information:

pmsim documentation - Contains the API reference and examples

Installation

This crates depends on russell_lab and, hence, needs some external libraries. See the installation of required dependencies on russell_lab.

Setting Cargo.toml

👆 Check the crate version and update your Cargo.toml accordingly:

[dependencies]
gemlab = "*"

Examples

For all simulations:

Heat: Arpaci Nonlinear 1d

Arpaci's Example 3-8 on page 130 (variable conductivity)

Arpaci V. S. (1966) Conduction Heat Transfer, Addison-Wesley, 551p

Test goal

This tests verifies the nonlinear solver for the diffusion equation with a variable conductivity coefficient.

Mesh

Initial conditions

Temperature T = 0 at all points

Boundary conditions

Temperature T = 0 on right side @ x = L

Configuration and parameters

Steady simulation
Source = 5
Variable conductivity (k = (1 + β T) kᵣ I) with kᵣ = 2

Note

The temperature at the right T = 0 (T_inf) must be zero in order to result in k(T_inf) = kᵣ as required by the analytical solution.
