*** General Introduction ***
In this comprehensive study, particle-resolved Direct Numerical Simulations have been performed on the gravitational settling of monodisperse solid spheres in a viscous fluid and triply periodic domain.
This data set contains the data to corresponding to  Shajahan, Tariq and Breugem, Wim-Paul, Inertial Effects in Sedimenting Suspensions of Solid Spheres in a Liquid.

*** Method : Direct Numerical Simulations (DNS) ***
Fully resolved DNS is carried out in a triply periodic rectangular domain filled with a viscous fluid in which immersed non-colloidal spherical particles are allowed to settle under gravity. 
The two phases in the simulation (fluid and particulate) are treated independently and coupled through a no-slip boundary condition enforced on the surface of the particle. 
The solution to the fluid phase is computed on a fixed Eulerian mesh and the moving surface of the particle is represented using a Lagrangian mesh that translates with the particle.
The simulation code is developed in house and written in FORTRAN90. 
MATLAB, PYTHON and PARAVIEW has been used to generate the figures presented in the article.


*** Data and scripts to generate figures ***
1. "plot_figs.m" is a MATLAB script to generate Fig. 5-13, and Fig 15;
2. The following python scripts are used to generate the 2D visualizations:
        plotRV_09Apr2023.py to generate Fig. 3  
        plotAF_15Dec2022.py to generate Fig. 4 
        plotKW_17Dec2022.py to generate Fig. 14a,c,e;  
        plotKA_17Dec2022.py to generate Fig. 14b,d,f;
3. 3D visualization data of particle position and vertial velocity (titled "*PartList.txt") corresponding to cases shown in Fig. 2 are included.
