SURFACE_STREAMLINE

name (string)

User-given name of the command. The instance of a given command is referenced using this parameter.

dataset (string)

Reference name as defined within the DATASET command. Used to indicate which dataset should be used to create the representation from.

seed_type (enum)

Defines the type of seeding operation

Options: from_surface, from_file.

surface_type (enum)

The type of surface that the surface_streamlines will be defined on. Note that the Part or Cut_Plane that the surface streamlines are drawn on must be created, using the Image command.

Options: parts (default), cut_planes.

cut_planes (list)

Cut planes to seed, used when surface_type=cut_planes.

List provided as comma separated values within curly braces. {“cut_plane_1”, “cut_plane_2”}

parts (list)

Parts to seed, used when surface_type=parts.

List provided as comma separated values within curly braces. {“part_1”, “part_2”}

calculation_direction (enum)

Defines the calculation direction for the streamline calculation.

Options: forward (default), backward or both.

num_seeds

(integer) Number of seeds to use when seeding the surface streamlines

seed_file (string)

Absolute or relative path and file name to the seed file, defines the x, y, z locations of the seeds to be used for streamline generation. Used when seed_type=from_file.

vector_function (string)

Vector field to define the streamline computation (velocity, time_avg_velocity, velocity_xz, time_avg_velocity_xz)

line_thickness (enum)

Thickness of lines for streamline display

Options: thin, medium, thick

contour_function (string)

Scalar quantity to be displayed on part (pressure, velocity, etc., Calculate Context Help). Used with color_type=contour.

legend_display (boolean)

Flag to toggle on or off the visibility of the legend

legend_min (real)

Minimum value in legend

legend_max (real)

Maximum value in legend

legend_location (enum)

Location of the legend on the image

Options: top_left, top_center, top_right, bottom_left, bottom_center, bottom_right, center_left, center_right

legend_use_local (enum)

Boolean to control the local legend range. If active, will set for local entity range.

legend_title (string)

Legend name to be used for the provided contour function, defaults to internal name

colormap_name (enum)

Colormap name to use for displaying the scalar function values

Options: Cool to Warm, Cool to Warm (Extended), Black-Body Radiation, X Ray, Inferno, Black, Blue and White, Blue Orange, Viridis, Gray and Red, Linear Green, Cold and Hot, Blue – Green – Orange, Rainbow Desaturated, Yellow – Gray – Blue, Rainbow Uniform, Rainbow, Rainbow Legacy
