MFIX simulation input and output files for the study of particle laden saline gravity currents

MFIX (Multiphase Flow with Interphase eXchanges) simulation input files and raw particle output files. Description of files 1. The directory "MFIX_Setup" contains the MFIX simulation input files for the two simulations Exp19 and Exp35. (MFIX input file (input and boundary conditions) *mfx & MFIX subroutines (*f) and geometry *stl) 2. The directory "time-averaged_slices" contain the time-average slices as *vtu files for Exp19 and Exp35 that can be opened using Paraview (open-source software). 3. The directory "depth-averaged and time-averaged data" contains the python code that reads the depth- and time-averaged data. Note the simulations were run with MFIX-20. The two simulation (Exp19 and Exp35) are 3D two-fluid model (TFM) numerical simulations of liquid-particle mixture, where the fluid and particles are saline water and silica particles, respectively. The finite-volume method is used to solve the mass, momentum and energy equations of the two phases and the solid-fluid coupling is done using drag and pressure terms. The MFIX code that is modified from the core code from the Department of Energy (DOE) is all present. The missing core code can be downloaded from the DOE department https://mfix.netl.doe.gov/.

MFIX input and output files for the study of granular rheology using mixtures with varying size, density, particle friction, and flow geometry

MFIX (Multiphase Flow with Interphase eXchanges) simulation input files and raw particle output files. The study was published in Breard, E. C., Fullard, L., & Dufek, J. (2024). Rheology of granular mixtures with varying size, density, particle friction, and flow geometry. Physical Review Fluids, 9(5), 054303. Description of files 1. Input particle input file (*.dat) 2. VELOCITY* and FORCES* files exported at 10 Hz The simulation are all done as pressure-controlled shear cells where the x and z axes are periodic boundaries, and the top and bottom boundaries are solid rough plates. The simulations are split in three types: MONODISPERSE, BIDISPERSE and TRIDISPERSE, where particle size (in mm), is indicated in the naming of the directory. The, in each set of simulation, the naming is with the following structure: 20N_0.0001ms, where the first number indicates the confining pressure (20 Newtons) and the second indicate the top plate moving velocity in the x-direction (0.0001 m/s). Note the simulations were run with MFIX-18. The MFIX code that is modified from the core code from the Department of Energy (DOE) is all present. The missing core code can be downloaded from the DOE department https://mfix.netl.doe.gov/.
