Introduction
This academic example introduces the numerical solution of eigenvalue problems. The Helmholtz equation (scalar and vector versions) is considered with homogeneous Dirichlet boundary conditions, for different basic geometries (i.e. linear, squared, circular and cuboid domain). These problems have a family of solutions. The eigenvalue solver used for this example provide the first eigenvalues and the associated eigenfunctions (i.e. the first possible solutions).
$\rightarrow$ To run the example, open main.pro with Gmsh.
