PyFLOWGO: An open-source platform for simulation of channelized lava thermo-rheological properties
Résumé
Lava flow advance can be modeled through tracking the evolution of the thermo-rheological properties of a
control volume of lava as it cools and crystallizes. An example of such a model was conceived by Harris and
Rowland (2001) who developed a 1-D model, FLOWGO, in which the velocity of a control volume flowing down a
channel depends on rheological properties computed following the thermal path estimated via a heat balance box
model. We provide here an updated version of FLOWGO written in Python that is an open-source, modern and
flexible language. Our software, named PyFLOWGO, allows selection of heat fluxes and rheological models of the
user's choice to simulate the thermo-rheological evolution of the lava control volume. We describe its architecture
which offers more flexibility while reducing the risk of making error when changing models in comparison to the
previous FLOWGO version. Three cases are tested using actual data from channel-fed lava flow systems and results
are discussed in terms of model validation and convergence. PyFLOWGO is open-source and packaged in a Python
library to be imported and reused in any Python program (https://github.com/pyflowgo/pyflowgo).
