User Controls
The following highlights the function of the Sub-face increment and
define full interfaces only user controls for the detection and identification
of a point-to-point continuous interface in a simple two block example as shown below.
In this figure the initial unprocessed interface objects at the boundary
common to both blocks are shown; the blue object corresponds to block 1 while the magenta
object corresponds to block 2. Note the for block 1, the coordinates of a single point have
been intentionally perturbed such that the offset to its corresponding point on the magenta
interface object exceeds the Same Point Tolerance.
With the Sub-face increment prescribed as 5, the define full
interfaces only checkbox activated and the Same Point Tolerance at the default
value, we press the Find one-to-one interfaces button to
compute the point continuous interfaces within the domain.
As indicated by the information written to the scrolling text field (shown above), we see that
no "one-to-one" interface objects have been defined. Though the majority of the
corresponding points within the blue and magenta interface objects are within the tolerance,
the fact that a single point comparsion falls outside the tolerance is sufficient to preclude
the defintion of a point continuous interface. This is exactly what has been prescribed via
the setting of the define full interfaces only checkbox. Note that the displayed
information identifies the maximum offset detected for the interface objects. It is also
apparent from this data that the detection algorithm compares each interface object to
every other interface object; though unecessary for full-face point continuity, this is
required for partial-face continuity detection.
We now deactivate the define full interfaces only checkbox and press the
Find one-to-one
interfaces button once again. The results rendered in the graphical display are shown
below.
Note that five point continuous interfaces have been defined on the common face
with each composed of an integaer number of like-sized chunks in both coordinate directions.
The smallest is a 1x1 chunk while the largest is a 3x2 chunk. The region encompassing the
point which had been perturbed has been excised and remains labeled as an unprocessed
interface.
