ParticleStart

ParticleStart

Defines a single particle's starting position and initial tracking step.

Attributes:

Name	Type	Description
id	int	User-supplied integer identifier for this particle.
x	float	Starting X coordinate (model units, global).
y	float	Starting Y coordinate (model units, global).
z	float	Starting Z coordinate — local normalized value in [0, 1]. 0.0 = cell bottom, 1.0 = cell top, 0.5 = layer midpoint. This is NOT a physical elevation. To convert: z_local = (z_physical - bot) / (top - bot). Passing a physical elevation (e.g. z=5.0 when top=10, bot=0) causes immediate ExitedDomain because 5.0 > 1.0.
cell_id	int	Zero-based index of the MODFLOW cell that contains the particle's starting position.
initial_dt	float	Initial time-step size for the adaptive tracker (model time units). Set to a small positive value; the solver adjusts automatically afterwards.
