The exhibition “Mathematics of Planet Earth” is part of the Lange Nacht der Wissenschaften (Science Night) at the Free University of Berlin - 13. June 2015
Dune Ash is an interactive simulation of a volcano eruption in Europe. You can place a volcano, add a wind field and explore the ash cloud dispersing in time.
This application computes an approximate solution to the dispersion of volcano ash over Europe after an eruption. Input data are set interactively and results are computed instantaneously.
Numerical simulations are used in geophysical applications like weather forecast or in predicting the propagation of pollutants in the atmosphere. Mathematical models that describe these phenomena are usually expressed in terms of Partial Differential Equations (PDEs). Computing solutions to systems of PDEs is a challenging task.
