Data underpinning: Can Multi-Threaded Flux Tubes in Coronal Arcades Support a Magnetohydrodynamic Avalanche?

Here is attached the relevant source code used for the numerical simulations undertaken in connection with the work underpinned. Here, these simulations use a numerical MHD code produced by Tony Arber, now at the University of Warwick, and others, adapted and configured in order to reflect the particular model at hand.
