DefVolc is a software for inverse modeling of volcano displacement data (InSAR, GNSS), whether the sources of displacement are fracture (fluid filled fracture or faults) or massive reservoirs. DefVolc is based on a 3D Boundary element method for elastic media combined with inversions, based on near-neighborhood inversion algorithms.
To be able to subscribe, you need a Project code. It can be obtained upon request by contacting Valerie Cayol (email@example.com). Alternatively, if you want to run the inversions on your own cluster, simply login with the Project code "anonymous".
To run the DefVolc pre and post-processor, you will need a computer with linux x86-64 and a version of gmsh more recent than 2.10.1.
You will need to install matlab Runtime corresponding to matlab version R2018b (https://ssd.mathworks.com/supportfiles/downloads/R2018b/deployment_files/R2018b/installers/glnxa64/MCR_R2018b_glnxa64_installer.zip)
To run inversions on your machine you will need a cluster but you can also run them on University Clermont Auvergne Mesocenter (https://mesocentre.uca.fr) using the following web interface.
In no event, shall the authors be liable for any claims, damages or other liability arising from, out or in connection with the use of defvolc.
