SURFACE_STREAMLINE

name (string)

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

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
