Detailed Description

Regular 2d grid loaded from a netCDF input file: monotonically increasing coordinates x and y plus a 2d field z stored in row-major (y, x) order, i.e. z[iy * nx + ix]. Used for the bathymetry and earthquake-displacement inputs of TsunamiEvent2d.

◆ inBounds()

bool tsunami_lab::io::NetCdf::Grid::inBounds	(	t_real	i_x,
		t_real	i_y ) const

inline

True if the query point lies inside the inclusive bounding box spanned by the cell-centre coordinates. Callers that want "zero outside" semantics (e.g. earthquake displacement that only covers part of the simulation domain) check this first.

◆ sampleNearest()

tsunami_lab::t_real tsunami_lab::io::NetCdf::Grid::sampleNearest	(	t_real	i_x,
		t_real	i_y ) const

Nearest-neighbor sample at (i_x, i_y). Always returns the value at the closest grid cell — clamps to the boundary when (i_x, i_y) lies outside the bbox, so callers wanting strict out-of-bbox handling must guard with inBounds().

Assumes the grid is uniformly spaced (the regular-grid assumption from the spec); the index is computed in O(1) from the spacing of the coordinate variables.
