Restart
UNTRIM
Adjustment of restart files produced by UNTRIM

Short Description of Functionality

Program RsMerge will adjust restart data produced by UNTRIM to a different grid:

  • Read restart data produced by UNTRIM
  • Selection of date and time
  • Write to restart file
  • grid file could be a part of the original grid, but it is not allowed to change the horizontal resolution
  • It is allowed to coarsen or to refine the vertical resolution
  • It is possible to use addends and/or multipliers to vary the restart data. It is also possible to do this only inside or outside of an arbitrary polygon.

The following physical quantities are part of a restart file produced by UNTRIM:

  • Water level
  • Horizontal velocity (normal component)
  • Vertical velocity
  • Salinity
  • Temperature
  • Hydrodynamic pressure
  • Suspended load (for each fraction transported)
  • Settling velocity

Input-Files

  1. General input data (file type rsmerge.dat)
  2. Restart file produced by UNTRIM (type dirz.bin, dirz.bin.i and dirz.bin.r))
  3. UnTRIM grid file used by UNTRIM (type untrim_grid.dat Untrim_Grid_Baw only)
  4. Vertical structure used by UNTRIM (type vertical.dat)
  5. UnTRIM grid file associated with the new restart file (type untrim_grid.dat Untrim_Grid_Baw only)
  6. Vertical structure associated with the new restart file (type vertical.dat)

Output-Files

New restart file (type dirz.bin, dirz.bin.i and dirz.bin.r)

Methodology

  • RsMerge uses the same procedures as UNTRIM to read the input restart file
  • The data read by RsMerges will be interpolated to the new grid taking into account the different vertical resolution
  • After interpolation it is possible to vary the data as defined by the user
  • Last step: writing the interpolated and varied data into the new restart file
