WVLagrangianParticles

Track particles and sampled fields through a WVModel velocity field.

---

Overview

WVLagrangianParticles stores periodic horizontal positions, optional vertical positions, interpolation choices, and fields sampled at each particle. Model particle facades construct the usual float and drifter configurations.

Topics

• Create an observing system
  • WVLagrangianParticles Create a Lagrangian-particle observing system.
• Inspect observed state
  • absToleranceXY absolute tolerance for the adaptive integrator in x-y directions
  • absToleranceZ absolute tolerance for the adaptive integrator in z direction
  • nParticles
  • trackedFieldNames tracked field names
  • trackedFields
  • x
  • y
  • z
• Advance the observing system
  • particlePositions Positions and values of tracked fields of particles at the current model time.
  • updateParticleTrackedFields One special thing we have to do is log the particle
