Construct discrete field with specified geometry.

Construct discrete field with specified geometryCreates a field with N-dimensional array storage and physical coordinate system mapping. The geometry (origin, discretization, bounds) is immutable after construction.

Parameters

dimensions	Size in each dimension [nx, ny, nz]
offsets	Global offset for subdomains (typically {0,0,0} for full domain)
origin	Physical coordinates of the first grid point
discretization	Spacing between grid points in each direction

domain field

// 64³ domain, unit spacing, origin at (0,0,0)
pfc::DiscreteField<double, 3> field(
    {64, 64, 64},           // dimensions
    {0, 0, 0},              // no offset (full domain)
    {0.0, 0.0, 0.0},        // origin
    {1.0, 1.0, 1.0}         // unit spacing
);
// Physical domain: [0, 64) x [0, 64) x [0, 64)
