Dune Ash

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.

This application was developed mainly at the department of applied mathematics at the University of Freiburg. The first version was built in June/July 2011 for the Freiburg Science Fair. Between September and November of 2012 additional features were added for touchscreen support.
