SMS:Particle Module Compute Grid Datasets

The particle module compute grid datasets dialog is accessed through the particle module data menu. The datasets are added to the active cartesian grid.

Currently the following grid datasets can be created in the particle module create datasets dialog:

• Particle Count
  • The number of particles in the Cartesian grid cell.
• Accumulation
  • The depth of particles in the Cartesian grid cell. The volume of particles is calculated using the particle mass and density dataset for particles which are inactive (based on the state dataset) and in the cell. The volume in each cell is divided by the area of the cell to calculate an average depth in the cell. No voids ratio is included at this time, however the Data Calculator can be used to change the resulting Cartesian grid dataset.
• Rate of accumulation
  • The change in accumulation (as described above) over time.
• Deposition
  • The change in depth of particles in the cartesian grid cell during the focus time. The volume of particles is calculated using the particle mass and density dataset for particles which have become inactive (based on the state dataset) during the focus time. This volume is then divided by the area of the cell to calculate an average depth in the cell. No voids ratio is included at this time, however the Data Calculator can be used to change the resulting cartesian grid dataset.
• Concentration
  • The concentration of particles in the Cartesian grid cell. The volume of particles is calculated using the particle mass and density dataset for particles which are active (based on the state dataset) and in the cell. This volume is then divided by the volume of the cell using the bathymetry and water surface elevation datasets.
• Exposure
  • The cumulative concentration relative to time in the Cartesian grid cell.
• Dosage
  • The exposure in the Cartesian grid cell during the focus time.
