# Multithreaded Poisson Equation Solver

## Introduction

This code is designed to numerically solve the  Poisson equation using the  mixed finite element method.  The code runs in parallel using multithreading through the Intel Thread Building Blocks.

**Note** 

This project improves upon  step-20 in the deal.ii tutorial by:

- Adding Neumann boundary conditions.

- Allow for multithreading to reduce runtimes.

 

## Requirements

The requirements for this software is deal.ii library version 8.4.0 or highe and CMake version 2.8 or higher.

## Installation

First obtain and install a copy of the dealii deal.ii library version 8.4.0 or higher. 

## Compiling

To generate a makefile for this code using CMake type into the terminal:

*cmake . -DDEAL_II_DIR=/path_to_deal.ii*

To compile the code in release mode use:

*make release*

## Running

To run the executable use:

*./main*
