## 14.11 Particle Flow Plot

Particle flows are useful for visualing fluid flows. The particles are seeded at the influx boundary of the flow, which is determined automatically. Everywhere the flow enters the mesh, a seed point is placed at the center of the corresponding facet. The particles then move with the flow, their motion determined by integrating the fluid flow.
• Data field: selects the data field that will be used for the particle flow plot.
• Color map: sets the color map used for coloring the glyphs.
• Allow Clipping: Allows the plot to be clipped by cutting planes or not.
• Seed step: The time step at which the particles are seeded.
• Velocity threshold: The minimum value for the velocity for seeding.
• Seeding density: Sets the density of particles at the seed step. When this value is less than one, particles are seeded on random facets, selected based on this density value.
• Step size: Sets the integration step size. A smaller value will produce more accurate flows, at the cost of a large computational expense.
• Show path lines: Show the path of the particles or not.
