Dear GiD users and GiD teams,
May I ask some questions.
1. I need to link GiD with Stoke's flow problem using 6-node triangle mixed p-u formulation (p=pressure, u= velocity vector vx,vy). Since p are only at corner nodes (3 DOFs per element) and u are at corner and midside nodes (12 DOFs per element). Can GiD list number of corner node and midside node separately ?
2. Can GiD show nodes and element meshes at the same time and in which mode (pre- or post- )?
Have a nice weekend
Best regards,

[GiDlist] How can I list number of Middle nodes and corner n

[GiDlist] How can I list number of Middle nodes and corner n
1- GiD cannot separate midnodes and corner nodes.
You must separate it inside your code (or an auxiliary program to be called from the bat file before your code)
It is possible to simulate two "sets" of elements, writting two times each quadratic element (one time as quadratic and one as linear):
For example, using a *.bas template similar to this:
NODES:
*loop nodes
*nodesnum *nodescoord
*end nodes
*set var cont=1
QUADRATIC ELEMENTS
*loop elems
num=*cont connectivities:*\
*for(i=1;ielemsnnode;i=i+1)
elemsconec(i) *\
*end for
*set var cont=operation(cont+1)
*end elems
LINEAR ELEMENTS:
*loop elems
num=*cont connectivities:*\
*for(i=1;ielemsnnodecurt;i=i+1)
elemsconec(i) *\
*end for
*set var cont=operation(cont+1)
*end elems
Note: The local numeration of the element nodes is hyerarchical, first are listed the corner nodes and after the midnodes
*elemsnnode return the nodes of a element, but *elemsnnodecurt returns only the number of corner nodes of a element.
This template is untested, it can contain some small bug.
2- By default, the nodes are not draw to speed the visualization. To show it in preprocess use the command:
escape escape escape View Entities Nodes
(write directly in the command line, or pressing the rigth buttons, hidden by defauld)
In postprocess you can draw only nodes or only elements, but not both.
Instead to show the nodes, you can show your labels (menu view-label inside pre or postprocess)

LEWIS, RANDEL E
[GiDlist] Gid Post Processor
The default Gid 7.1 Post Processor provides stress components Si, Sii
and Siii in addition to those obtained from the solid model *flavia.res
file. These are not defined in the supplied documentation. Are they
Principal Stresses derived from the X, Y and Z stress components of the
*.flavia.res file?

[GiDlist] background job execution from GID
Dear All,
I am using the tcl command :
exec $executable $arg1 $arg2 $arg3 & NUL: &
This command seems not to be a background executing command. Whenever I
used it, the GID window is "frozen" !So, my questions are:
How is it possible to run a backgroung job ?
And how is it possible to know that this job is over ?
If somebody has got a response, it will be interesting for me (us).
Thank you.
G.W.R. Geis

Yes,
they are the main stresses of the tensor matrix.
given a matrix result, GiD calculates its eigen values and eigen vectors.
Si, Sii, Siii are ordered by its eigen values.
yes, sorry, the documentation is too brief about this question, we'll include
an explanation about this in the documentation.

[GiDlist] background job execution from GID
Your command execute the process in background !!
Try for example to run a Windows notepad, writting in the command line this:
-np- exec "c:/winnt/system32/notepad.exe" & NUL: &
Note: -np- is to indicate a tcl command instead a word to process.
(It is supposed notepad.exe located in c:\winnt\system32, this location can be changed)
This open a notepad text editor without block GiD (the process work in background)
Try now to run whitout the ampersand:
-np- exec "c:/winnt/system32/notepad.exe"
Then GiD is locked until exit notepad.
