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
