Physics-Informed Neural Networks for Depth-Averaged Avalanche Dynamics

This npz file stores the TITAN2D simulation for one mass angle. There are four such files in total, one for each combination of mass and angle used in the validation case: 1 kg at 10 deg, 1 kg at 15 deg, 2.5 kg at 10 deg, and 2.5 kg at 15 deg. Inside each file, there are four arrays: t: the sequence of simulation time steps. x_c and y_c: the spatial coordinates of the cell centres on the computational grid. H: the flow (avalanche) height at every grid cell, recorded at every time step.
