The video shows an Euler equation solve in 2d on the unit square. As initial condition, we alter the internal energy of the system such that it displays the Durham code of arms. Look out for the ExaHyPE logo however! The problem is solved on a dynamically adaptive grid and it applies a limiter along the shock fronts. We used it as "official" video throughout the inauguration ceremony of Durham's Computer Science department.
The video shoes the solution to the elastic wave equation in a region of the alps around Trento.
This video shows elastic waves propagating through the earth. Normal and shear stress are shown on the left and on the right.
