Energy Files

• energy.dat: Contains the energy of fluid and particles, listed in columns with this order: time, particle mass, particle translational kinetic energy, particle rotational kinetic energy, particle potential energy, fluid mass, fluid kinetic energy, fluid potential energy, fluid mass inside particles, fluid kinetic energy inside particles, fluid potential energy inside particles.

General Files

• export.dat: A generic file that reports some of the info that are printed on screen by the code.
• fluidCenterOfMass.dat: Contains the position of the fluid centre of mass, at each instant.
• particleCenterOfMass.dat: Contains the position of the particle centre of mass, at each instant.
• fluidFlowRate.dat: Contains the total fluid flow rate in each direction, at each instant.
• particleFlowRate.dat: Contains the total particle flow rate in each direction, at each instant.
• fluidMass.dat: Contains the total fluid mass, at each instant.
• force.dat: Contains the integral of all collisional forces exchanged by the particles, and of all hydrodynamic forces exchanged by particles and fluid at each instant.
• maxOverlap.dat: Contains the maximum and mean overlaps between particles (both in absolute terms, and scaled by the particle radius), registered at the printing time.
• maxDtOverlap.dat: Contains the maximum and mean overlaps between particles (both in absolute terms, and scaled by the particle radius), registered within two consecutive visualization intervals.
• maxFluidVel.dat: Contains the maximum fluid speed recorded at each instant.
• maxParticleVel.dat: Contains the maximum particle speed (translational and rotational) recorded at each instant.
• wallForce.dat: For each wall included in the simulation (e.g. boundary walls), reports the total force exerted by particles and fluid, at each instant.
• maxWallForce.dat: For each wall included in the simulation (e.g. boundary walls), reports the maximum total force exerted by particles and fluid, registered within two consecutive visualization intervals.
• plasticity.dat: Shows which percentage of the fluid cells is currently in a plastic state (pre-yield). The code defines nodes in a plastic state as those whose viscosity is more than 95% of the maximum allowed viscosity.
