Supplemented computer code
Introduction
This is the supplemental computer code for the book "Electromagnetics with
finite elements: static problems", ISBN 978-9090380933. The code contains
numerical experiments that illustrate application of the finite element
method to problems in electro- and magnetostatics. A number of boundary
value problems formulated in terms of electric scalar potential, total
magnetic scalar potential, reduced magnetic scalar potential, magnetic vector
potential, and current vector potential are solved numerically on two- and
three-dimensional problem domains.
The documentation of the computer code and the numerical experiments
exists in a form of online Logbook. The Logbook can be found at
https://cembooks.nl.
Installation
To run the code do the following.
1) Get [deal.II](https://dealii.org) and install it. The best is to build the
latest version of deal.II from the source by following the
installation instructions available at [www.dealii.org](https://dealii.org).
No optional interfaces to other software packages are needed. The default
configuration will do.
Set an environment variable by adding the following
line to /etc/environment file:
export DEAL_II_DIR=/path/to/dealii
where /path/to/dealii is the directory in which the dealii is installed. Reboot.
Check if the variable exists by typing the following into CLI:
printenv | grep DEAL
Check if the version of deal.ii in the CMakeLists.txt files is correct. To do so,
change into static/ directory and type the following:
find . -name "CMakeLists.txt" -exec grep "find_package(deal.II" {} +
If the version is not correct, change it. For example, to change the version
from 9.3.2 to 9.5.2 type the following into CLI:
find . -name "CMakeLists.txt" -exec sed -i 's/deal.II 9.3.2/deal.II 9.5.2/g' {} +
2) Install gmsh, gnuplot, texlive, and GNU parallel. This can be done as the
following:
sudo apt-get install gmsh gnuplot texlive parallel
3) Install a program for viewing vtk files. [Visit](https://visit.llnl.gov)
software package of the Lawrence Livermore National Laboratory is a good option.
4) Extract the archive of the supplemental computer to static/ directory.
5) Change into the static/ directory and run
./clean
./setup
./build
./run-all
This will build and execute all numerical experiments. The last two steps will
take some time... Alternatively, you can build and run only the experiments you
are interested in. To do so, change into static/ and run
./clean
./setup
Then change into the directory of the experiment you are interested in, say
mms/. In this directory change into build/Release/ and run
./clean
./build
After that change into mms/bin/Release/ and run
./run-all
This will execute the mms experiment. The results of the simulations are in
mms/bin/Release/Data/ directory.
