In/Output
| 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.

|
| 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.

|
| 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.

Process
| 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.
