III. Cycle géodynamique des volatils
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…
4. VolcFlow as a script
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…
5. Tsunami
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 :…

2. Collapse
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…
1. Dambreak
%A simple example to simulate a dambreak in 1D %basic instruction to write a VolcFlow file nrow = 3; %equations are in 2D. At least 3 lignes (or columns) should be defined, even for 1D simulation ncol = 500; %number of column of the simulation dx_horiz = 3/ncol; %defines the space step (in m)…
