[ GiDlist ] how to change the sense of element connectivity?

To write the elements list, 3 options are possible:

*ElemsConec
*ElemsConec(swap)
*ElemsConec(1) *ElemsConec(2) *ElemsConec(3) *ElemsConec(4) ...

With the last option, you can construct the elements list as you
prefer.


The third option is the most flexible one but it works only if the
coordinates are in the +ve direction.

I tried a simple 2D mesh with two different coordinate systems, one with
+ve(y) and the second with -ve(y). After setteing up the configuration file
to write the *elemsconec clockwise, only the one with the +ve y worked!

Any explanation?

Hi,

How do I take control over the sense of element connectivity written to
the calculation file using *EelemsConec?
and,
Is it possible to change that sense to be clockwise or anticlockwise for
both 2D and 3D meshes.

Anybody's help will be appreciated.

thanks
