To compile the code you can create a makefile or configuration files for the I DE of your choice using the tool CMake (available at https://cmake.org/).

Please make sure you have the Eigen library (available at http://eigen.tuxfamily.org) installed and the environment variable CMAKE_PREFIX_PATH contains the installation directory of Eigen.

Exercises

For the programming exercise, several files are of importance.

Exercise 1

The main function and basic structure are located in ex1.cpp. Locations where the code should be filled in can be found in the Todo List.

To visualize the results, you can use Paraview or any other program that can visualize files in the legacy Vtk format.

Hints

ex1.cpp uses the constant right hand side f by default. If you want to use the second function, replace createMaskedConstantRHS (line 62) by createMaskedNonConstantRHS.
In CMake, there are two build types: Debug (needed for debuggers to work correctly) and Release (faster program execution). You can switch between those types by setting the CMAKE_BUILD_TYPE variable.
After downloading and extracting Eigen, the EIGEN_INCLUDE_DIR variable (in CMake) should be set to the directory containing the "Eigen" and "unsupported" folders.
CMake: After setting the source and build directory click "configure", then "generate".
