Parameters in this block control the properties of the grid.
They are accessed by the function init_grid_block.c.
- nxzones: number of grid points
- x1min: X-coordinate of left-edge of first cell
- x1max: X-coordinate of right-edge of last cell. The entire
computational domain spans
, the grid spacing is
, and the center of the first cell is located at
- ibc_x1, obc_x1: integer flags for boundary conditions applied
at ``inner" (left) and ``outer" (right) edges of grid. Currently three
values are implemented: 1 = reflecting, 2 = inflow and outflow (projection),
and 4 = periodic.
