BOOST_AUTO_TEST_CASE

VibratingTruss1DFirstEigenfrequencies

)

Computes the first squared eigenfrequencies of a vibrating truss with free ends and compares with analytical solution.

Since the true solution and the approximated one will differ on smaller scales / higher frequencies only low frequencies are compared.
