Model description
| Model type: | Single model |
| Description: | Three dimensional simulations of the Turbidity currents using DNS of incompressible Navier-Stokes and transport equations. |
Technical information
| Supported platforms: | UNIX, Linux |
| Programming language: | C |
| Model was developed started from: | 2006 and development still takes place |
| To what degree will the model become available: | As code |
| Current license type: | GPLv2 |
| Memory requirements: | Typical ratio: 250,000 nodes requires 1 Gbyte |
| Typical run time: | -- |
Input / Output description
| Input parameters: |
|
| Input format: | ASCII |
| 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). |
| Output format: | ASCII, Binary |
| Post-processing software (if needed): | 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 (if needed): | Yes, Paraview |
Process description
| Processes represented by 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. |
| Key physical parameters & equations: | Incompressible flow equations: Navier-Stokes with Boussinesq approximations. Transport equation to describe the motion of particles (or Salanity or Temperature). |
| Length scale & 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. |
| Time scale & resolution constraints: | -- |
| Numerical limitations and issues : | -- |
