Active when pointtype is set to arrow. Determines the direction in which the arrow points.

The arrow scaling: Proportional uses the actual arrow length, normalized a unit length, and logarithmic a length proportional to the logarithm of the arrow length.

If arrowscalefactor is true: the length scale factor

If true, arrowscale is used; otherwise the scale factor is computed automatically.

Whether to specify a manual absolute tolerance for the position. automatic indicates that the absolute tolerance for the position is the mean of the lengths of the bounding box of the geometry multiplied by the relative tolerance.

Absolute tolerance for the position. Active when atol is set to manual.

Vector of values from 0 to 1 to describe the starting points. Active when bndmethod is set to coord. Available in 2D only.

Active when posmethod is set to bnd. Available in 2D only.

Active when pointtype is set to comettail. Determines the direction in which the comet tail points.

The uniform color to use for lines. Active when linecolor is set to custom.

The uniform color to use for points. Active when pointcolor is set to custom.

The description of the expressions in expr. Is used in the automatic title.

Whether the title contribution should contain the description when titletype is custom

Particles are released at these intervals when dropmethod is set to freq.

The specific times when to release particles. Used when dropmethod is set to times.

The maximum time step. Active when stepsize is set to manual.

The initial time step. Active when stepsize is set to manual.

If inheritplot is not none: Determines if the arrow scale is inherited.

If inheritplot is not none: Determines if the deformation scale is inherited.

If inheritplot is not none: Determines if the sphere scale is inherited.

If inheritplot is not none and linetype is tube: Determines if the tube scale is inherited.

Time corresponding to last selected solnum for transient levels.

The time to use, for transient levels. Available when data is not parent and the underlying data is transient.

If arrowlength is logarithmic: The ratio between the maximum arrow length and the arrow length below which no arrow is drawn.

The index of the solution to use, per level, or interp, but only for transient solutions. Available when data is not parent and the underlying data has multiple solutions.

The maximum number of steps to use in the particle simulation. Active when maxstepsactive is set to on.

Whether to manually specify the maximum number of steps used in particle simulation. off indicates that the limit varies in this way: for static flow fields, the algorithm uses the value 1000; for time-dependent flows, there is no upper limit of the number of steps, and the particle simulation goes on until it reaches the end time.

stick plots the points on the boundary at the exit point, and disappear does not render these points at all.

The index of the solution to use. Available when data is not parent and the underlying data has multiple solutions.

If data is a local dataset with nontrivial data, specify solutions manually or take them from the parent plot group.

Only affects time-dependent problems. When set to on, this property freezes the time and considers this a static flow field.

The maximum time at which to end the particle-tracing simulation for static flow fields. Active when statictendactive is set to on.

Whether to specify the end time for static flow fields automatically. (For time-dependent flows, the automatic end time is the last time that the time-dependent solver returns.) When set to off, there is no upper limit of the time. In this case, the particle simulation goes on until all particles exit the geometry or the simulation reaches the maximum number of steps.

Whether to specify initial (hstart) and maximum (hmax) time step manually.

Time corresponding to last selected solnum.

The time to use, for transient problems. Available when data is not parent and the underlying data is transient.

Active when pointtype is set to comettail and tailscaleactive is on. Specifies the manual scale factor with which the comet tail expression is multiplied.

Active when pointtype is set to comettail. Specifies whether manual tail scaling is enabled.

The title to use when titletype is manual

auto, if the title should be computed automatically. custom, if the title should be computed automatically, but customized. label, if the title should be the plot group’s label. manual, if the manual title should be used (the title property). none, if no title should be displayed.

Manual start time. Active when tstartactive is set to on.

on indicates a manual start time (set in the tstart property). Off indicates that the start time becomes either the first time value that the time-dependent solver returns or 0 for stationary flows. Available when dropmethod is set to once or freq.

Whether the title contribution should contain the type when titletype is custom.

Absolute coordinates in the x direction, active when posmethod is set to start.

Absolute coordinates in the y direction, active when postmethod is set to start.

Absolute coordinates in the z direction, active when posmethod is set to coord. Available in 3D only.
