[GiDlist] Postprocessing data

[Smith, Mark]

Hi Miguel
Thanks for the reply.
Tcl/Tk is obviously a good powerful language, it's me that's the problem, I'm getting old & it's like nothing else I've used ;-( I find Lua much easier.
I must check out the latest version as I'm still using 7.7.7b.
Regards
mark

Hello,
In the last 8.0.2 version of GiD there is a window which can be popped up with 'Windows-Create result..." which lets you operate between results with the basic operators: +, -, * and /.

As Ramón said, there will be a new and more powerful window.

If you look into the file
'%GiDInstallDirectory%/scripts/PostCreateResult.tcl' you'll find the three functions which let's you retrieve, delete and create results inside GiD:
GiD_Result get ...
GiD_Result delete ...
GiD_Result create ...
(Look for these names at http://www.gidhome.com/support/gid_18.subst#SEC303)

With these functions you can get your results, call your program written in the language you want, and send them back to GiD.

Well, about TclTk, it depends on the purpose of the language it was designed for.
It's true that TclTk is not so data-oriented, or if you like, object-oriented as Python, string-oriented like Perl, or web oriented like PHP, but it's its own powerful tools. Try managing lists or hash tables in one of those languages; lets say create a graphic user interface for your program.

So the choosing of one scripting language versus another depends of what you're looking for. We were looking for a scripting language which lets us manage information and the graphic interface very easily, and that's TclTk.
Every language has its own fancy whims which everyone should put up with.

Best regards

Miguel

Hi Gid Team

Is it possible to extend the post-processing capability by allowing existing data to be plotted in different ways. For example if I had 3 scalar quantities on nodes say displacements x,y & z it would be nice to be able to plot the magnitude of the displacement on a displaced mesh.
In fact it would be useful to post process results by applying any mathematical process on the existing results to form a new output. At the moment you seem to have to write a new results file capability in the solver?
A script language would be useful & not Tcl/Tk which I find to be the most unintuitive language invented!

Hi,

In my GiD-post file I have 2D quadrilaterals and 1D line elements, both
1st order. On the 2D elements there is defined a nodal result
(elecPotential), as well as an element result (elecFieldIntensity),
which is just computed for the central point of each element. I use GiD
8.0.1 on a Linux machine.

When I now try to use contour lines, I can only visualize the nodal
field, whereas the element results gives no lines at all. Is this
intended or is there something wrong with my definition of the Gauss
points? The file was created using the gidpost library 1.7 (see attachment).

Additionally I have results defined on 1D line elements within this
grid. These results I can only visualize with a normal contour fill,
because smooth contour fill gives only 0's. Is this a correct behavior
or is there a possibility to smooth contour fill also the values of 1D
results onto a 2D grid?

The files of concern are attached in .tar.gz format.

Thanks for your help.

Regards,

Andreas

Hi,
i'll check it.
In the meantime ¿have you tried the
ftp://www.gidhome.com/pub/gid/Linux/gid8.0.2-dyn-kernel2.6.tar.gz or
ftp://www.gidhome.com/pub/gid/Linux/gid8.0.2-dyn-kernel2.2.tar.gz version?

Dear GID team,

I have cehcked that the new version of GID plots quadratic line elements
very nicely, showing curved elements when they are indeed curved.
However, if I am right, it is not so for quadratic quadrilaters or
triangles. Do you have any plans to plot quadratic body elements in
future versions?

Many thanks,

Jose Munoz

[escolano]

If you set the "quadratic visualization" mode, then as you said, lines are showed curved, and also edges of
triangles/quadrilaterals, and the interior each triangle/quadrilateral is showed with four lineal subtriangles/subquadrilaterals.
We don't planned to show this interior "body" more accurately, because it will be too expensive to draw (usually there is a lot of
elements), but maybe we can think to add some user variable to set this element visualization accuracy.

Hi,

I have tried the 8.0.2. version, but the problem is the same. If you
could please check, what's the problem with the element data and contour
lines?

Andreas
