MPM-CFD entrainment: Processed data and visualization

Data supporting "The role of dilatancy and permeability of wet bed sediments eroded by a granular flow on erosion and runout: Two-phase MPM–CFD simulations". Content:

- The full simulation results cannot be included as a supplementary material as the files are too large. However, we include the input files, which can be run with the MPM–CFD code (https://github.com/QuocAnh90/Uintah_NTNU/tree/1.0). We also include the processed data from the simulations, which can be used for visualization. 

- Processed data from the MPM–CFD simulations (particles positions and displacements, pore pressure).

  Each simulation is named with a code. For instance:

dry / wes: dry or wet simulation

30: indicates the effective friction angle

k-3: -3 is the Log of the D_p parameter

Name: data type of the particles: 

particlesX: position

particlesDispl: displacement

particlespwp: pore pressure (absolute value, including "atmospheric pressure"), corrected with a default value of p_atm=101325 Pa

particleStress: effective stress tensor

pressCC: pore pressure (absolute value, including "atmospheric pressure"

m: material: 1=flow; 2=bed; 0=any material

t= (time(s)+1) * 10

- Matlab files to process the data and create the figures.

The code Erosion_runout.m serves to plot flow and particle displacements and to calculate the flow runout and erosion volume

The code pwp.m serves to plot pore pressure ratio and calculate the median pore pressure ratio

The code pwp_evolution.m served to plot the time evolution of the median value of the pore pressure ratio
