Input - Output description
Describe input parameters Input parameters:
  • Geometrical parameters: Nx, Ny, Nz.
  • Grid: Uniform or nonuniform.
  • Flow Parameters: Reynolds, Peclet
  • Particle Parameters: Settling velocities.
  • Flags: Output writing flags. Inflow/Outflow to the domain flags.
Input format ASCII
Other input format
Describe output parameters Depending on the flags indicated in the input file, typical flow quantities are stored to the file at the given time steps.

Velocities, Pressure, Concentration (of the particles).
Depending on the problems, some other quantities could be stored too.

Output format ASCII, Binary
Other output format
Pre-processing software needed? No
Describe pre-processing software
Post-processing software needed? Yes
Describe post-processing software Yes, a C code is developed for this gvg3Dp in order to convert the raw binary data into the xml-vtr format which can be read using paraview software.
Visualization software needed? Yes
If above answer is yes
Other visualization software Paraview


Process description model
Describe processes represented by the model Any type of turbidity (or gravity) currents could be modeled with this code. Is also handles the flows passing complex topographies, inflow/outflows too.
Describe key physical parameters and equations Incompressible flow equations: Navier-Stokes with Boussinesq approximations. Transport equation to describe the motion of particles (or Salanity or Temperature).
Describe length scale and resolution constraints With the current version of the code (DNS and no turbulence model) we are restricted to low Reynolds numbers. Up to maximum 10,000.
