deal.II is a C++ program library targeted at the computational solution of partial differential equations using adaptive finite elements. It uses state-of-the-art programming techniques to offer you a modern interface to the complex data structures and algorithms required.
Let's say you've unpacked the .tar.gz file into a directory /path/to/dealii/sources. Then configure, compile, and install the deal.II library with:
$ mkdir build
$ cd build
$ cmake -DCMAKE_INSTALL_PREFIX=/path/where/dealii/should/be/installed/to /path/to/dealii/sources
$ make install (alternatively $ make -j<N> install)
$ make test
To build from the repository, execute the following commands first:
$ git clone https://github.com/dealii/dealii
$ cd dealii
Then continue as before.
A detailed ReadME can be found at ./doc/readme.html, ./doc/users/cmake_user.html, or at https://www.dealii.org/.
The tutorial steps are located under examples/ of the installation. Information about the tutorial steps can be found at ./doc/doxygen/tutorial/index.html or at https://www.dealii.org/.
deal.II includes support for pretty-printing deal.II objects inside GDB.
See contrib/utilities/dotgdbinit.py or
the new documentation page (under 'information for users') for instructions
on how to set this up.
