FLDAdvect2D

Overview

Generates particle animation based on 2 component or 3 component vector data.

Description

Generates particle animation based on 2 component or 3 component vector data. Th e shape of the particle is a diamond shape (8 surfaces). The direction in which the particles are advect ed is determined by calculating stream lines in the neighborhood of the defined starting point. The particles are advected along the stream lines.

Input Ports

fld_in
AVS/Express Field(2D structured type vector data)

Output Ports

obj_out
AVS/Express DataObject

Parameters

Visible
switches on and off the display of particles.

Reset
resets all parameters.

Save MicroAVS Visualized Geometry
saves data in a MVG file.

Help
displays help.

Select Data
Selects the data to be distributed in the X, Y (Z) directions. D ata components are in the X, Y and Z directions starting from the top in order. Further, the number of components should be at least two or three.

Calc All
The starting point at which particle advection begins is defined to be all the points.

display line
A line is displayed to indicate the starting point for particle advection.

rot
the line is rotated along the plane in which the data exists.

trans x
The line is moved along the X direction in the data plane.

trans y
the line is moved along the Y direction in the data plane.

line length
Sets the scale of the line length.

dim
Defines the number of cells on the line. The line is div ided at these points, and each of these points become the starting points of the cells.

set line center
positions the line vertically in the center of the X axis.

Control Buttons

Reset - resets the system to the initial state of time.

Stop - stops particle advection.

Run - plays back the advection once.

Cycle - plays back cyclically. When the end point is reached, the system goes back to the starting point and this is done repeatedly.

color
The glyphs are colored based on the vector values.

glyph scale
sets the size of the glyph.

start time
Defines the start time at which particle advection begins along the stream lines.

end time
Defines the time at which particle advection ends.

step
Defines integral time (time step).

N-segments
Defines the number of time steps within a grid.

Max-segments
Defines the total number of time steps.

order
Defines the order of integration.

Display Trace
Drawing tailed line.
