plot_exact.py

Python script that reads the data in exact_data{N}.txt and plots the exact solution of the Poisson equation, u(x). Output: 'figures/exact.pdf'

general_vs_exact.py

Plots the general approximations from approx_general.txt against the exact values exact_data.txt. Output: 'figures/general_vs_exact.pdf'

errorplot.py

Our results are summarized in a [project report](report_project2.pdf)

Description

The main topics of this project was: - scaling of equations - eigenvalue problems - unit testing

We considered a horizontal beam of length L fastened with pin endpoints. The vertical displacement were denoted as u(x), and we were interested in studying the different static shapes the beam (u(x)) can take due to an applied force at the endpoint directed into the beam.

The situation is described as

Folder for results from main.cpp

Problem 9:The filenames indicate the parameters for problem 9:

The filenames indicate the parameters in the following way:

{type of algoritm}\_i\_{iterations}\_d\_{duration}\_p\_+{particles}+\_pi\_+{interactions}+

This folder contains all datafiles produced by our source files. These datafiles are used to plot the figures you can find in the 'figures/' folder.

Folder content

This folder is the default save location for all the datafiles produced by the prorgam. As the datafiles are large binary files, we are not able to upload them to git. This folder is therefore empty, and may just contain a dummy file so that the folder is included if the repository is cloned.
