Post by Andrea Calaon »

Hello Enrique,
here is a very compact sample.

The geometry is a unitary cube:
Points
1 0.000000 0.000000 0.000000
2 1.000000 0.000000 0.000000
3 0.000000 1.000000 0.000000
4 1.000000 1.000000 0.000000
5 0.000000 0.000000 1.000000
6 1.000000 0.000000 1.000000
7 0.000000 1.000000 1.000000
8 1.000000 1.000000 1.000000

The condition Contour_Line has been applied to all the model lines.
I then mesh with a Structured mesh all the surfaces using 2 as number of cells for all the lines.
The answer to the command "-np- WarnWinText [.central.s info conditions Contour_Line mesh]"
is here included in tabular form (with the elements reordered to check how many times each appears).
Every element in this particular case should appears 2 times, since it has two different lines with the
Contour_Line as boundary. But for example elements 5, 6, 10, 11, 15, 19, 20 appear only one time, and
element 13, 17, 18 are completely missing.

At this moment, the conditions 'over face elements' are implemented only to
be transferred to the elements on boundary faces,

For surfaces are considered as boundary only the lines with
"higherentity"=1, (or lines with "higherentity"=1 shared
by two surfaces with different material). (use menu Meshing-Boundaries to
visualize this boundary)
Your case is a "closed" cube: all lines are considered as interior, and
some conditions are transferred only to
some elements, not to all elements.

At this moment you must use some trick, for example to assign a different
material to each surface to
force the interface lines be considered as boundary.

We are currently working to avoid this limitation for the next beta version.
