MinVoellmy is a lightweight, open-source model for simulating rapid mass movements such as snow avalanches and rock avalanches. It implements the modified Voellmy rheology proposed by Hergarten (2024a). Details of the implementation are described by Hergarten (2024b). ttminvoellmy is a MATLAB-based TopoToolbox (Schwanghart and Scherler, 2014) interface to the MinVoellmy 2D solver which makes simulation and visualization easy-going.
You can either download the entire toolbox and add the folder toolbox and its subfolders to the search path. Alternatively, download the latest release of the toolbox (.mltbx). Once, you double-click the toolbox, it will be installed to MATLAB's add-on folder.
Note that TTMINVOELLMY requires TopoToolbox to be installed.
To get started, check the folder examples. There are three examples that should be rather self-explanatory.
