[ GiDlist ] nodal coordinates

[ramsan at stamp.cimne.upc.es]

Hello,

In the latest version, the tolerance for the z coordinate is much
smaller. Get the lattest beta in the 'GiD web page download Beta
versions' and this problem should be fixed.

Best regards,

thanks for the prompt reply,
unfortunately it doesn't seem to work. I get three coordinates, but the
third one is always zero. I checked with the write mesh option and there
the z values are different from zero.
what else can I do?

Hi,

I'm dealing with surfaces of sliders in computer harddrives. I' using GiD
for meshgenerating. The surfaces are three dimensional. when I use the
Write Mesh command, my nodes have Three coordinates, if I use the command

*loop nodes
*NodesNum *NodesCoord
*end

in the ".bas" file for the same model Gid writes only the x & y coordinate.
How can I solve this problem.

The differences in the level of two adjacent surfaces are pretty small.
(0.001 mm)
Is there an option that has two be set?
I don't have problems if the surfaces levels are bigger.

The problem is that GiD uses an epsilon on the Z axis to determine if
the problem is a 2D one or a 3D one (if all the geometry is defined
inside this epsilon, the problem is a 2D one).

But you can get the three coordinates of the nodes with something like this:

*loop nodes
*NodesNum *NodesCoord(1) *NodesCoord(2) *NodesCoord(3)
*end nodes
