Rôle des serpentines dans le recyclage pendant la subduction. L’étude des serpentines alpines permet d’étudier le transfert d’éléments ainsi que la circulation des fluides pendant la subduction jusqu’à 100-150 km de profondeur. Pendant l’altération océanique, elles piègent des éléments mobiles tels que (B, Li, As, Sb, Rb, Ba, Cs, Sr, U et Pb) qui permettent…
It is possible to use VolcFlow as a script if you need to run several simulation, in a probabilistic approach for example. Here, lava source conditions are defined randomly. Simulation are done and data are saved. At the end, a map is generated. Red color = affected by all the simulations, blue = by just…
Simulation of a tsunami This example also shows how to use a image to define the initial thickness. You MUST use the double upwind scheme for tsunami simulation (doubleUpwind = 1 – a simple scheme would smooth the results). download the image here and add it in the same folder than the input file :…

This example simulates the collapse of a mass, which is initially square shaped. The plastic rheology has been chosen. The artificial topography is defined with a mathematical function. initial shape final shape Copy/paste these lines in the editor of Matlab. Save the .m-file, run VolcFlow and chose the file. %A simple example to simulate a…
