Description
The "Contour Mesh" module inputs a 2D field and colormap.
This module looks like the "field to mesh" module.
This module creates the contour only Fluid AREA (of CFD).
Note!
This module inputs 1-vector or 2-vector field.
1-vector :This data is scalar value(for contour).
2-vector :The first component is scalar value(for contour),
and the second component is flag data(for CFD obstacle).
The second component tells which digit (0 or 1) is
in the node as flag data.
The flag data of the nodes is as follows.
1 means the fluid node and 0 is the non-fluid node.
1---1---1 +---+---+
+ + + + + +
0---0---1 +---+---+
+ + + ----> | |
0---0---1 +---+ creates only this area
data(1,i,j) = the scalar data for contour mesh
data(2,i,j) = the flag data for CFD node
1 : fluid node (live)
0 : non-fluid node (obstacle)
1. The min/max parameter controls the color of contour mesh.
2. When the color option parameter is ON, the contour color
is set from the input colormap data(lower/upper).
You cannot change min/max dial.
Set the lower/upper dial of the "generate colormap" module.
When you press the color option, the color is set by the input colormap
(lower/upper dial). When this button is off, the color is determined
by the min/max dial.
Parameters
On/Off Determines the visible/invisible.
just If pressed, the min/max dial is automatically set
the minimum/maximum value of input field.
color option Controls the color of contour lines.
min Sets the minimum color of contour.
max Sets the maximum color of contour.
information Displays the information of minimum/maximum value.
