Simulation Grid Choices for BATSRUS Model of the Magnetosphere

CCMC is offering several grids for BATSRUS runs using 8x8x8-cell blocks:

• Overview (SWPC real time) grid with 1,007,616 cells:
  
  Simulation box size:
  -224 R_E < x < 32 R_E
  |z|, |y| < 128
  The finest resolution for this grid in the near-Earth magnetosphere is 1/4 R_E.
  
• Dayside grid with 1/16 R_E resolution and 18,558,89976 cells
  Simulation box size:
  -224 R_E < x < 32 R_E
  |z|, |y| < 128
  The finest resolution for this grid in the near-Earth and dayside magnetosphere is 1/16 R_E.
  

CCMC is offering three grids for BATSRUS runs using 6x6x6-cell blocks:

• Grid with 755,136 cells:
  
  Simulation box size:
  -250 R_E < x < 33 R_E
  |z|, |y| < 48
  The finest resolution for this grid is 1/4 R_E around the earth. Finest resolution in near-tail and magnetopause is 0.5 R_E.

Zoom:

• Grid with 1,958,688 cells:
  
  Simulation box size:
  -250 R_E < x < 33 R_E
  |z|, |y| < 48
  The finest resolution for this grid in near-tail and dayside magnetopause is 1/4 R_E.

Zoom:

• High-resolution grid with 9,623,552 cells:
  
  Simulation box size:
  -352 R_E < x < 32 R_E
  |z|, |y| < 96
  The finest resolution for this grid in near-Earth is 1/4 R_E and 1/2 R_E in the dayside and near-Earth nightside magnetosphere and magnetosheath.

  

You can examine the grids in more detail by viewing the results of a particular run and choosing the "Show simulation grid" option.

Each grid has a simulation run duration limit between 24 hours (1 day) and 168 hours (1 week). For simulations longer than a day only lower resolution grids may be available.
If you require a special grid, please specify so in the "Special Request" box at the end of run submission by referring to a previous run using the desired grid or by describing the resolution required for a spatial region. You can also contact the CCMC staff with your request.
