GiD forum

Hi GiD staff,

I'm working on a *.tcl file and I'm trying to write a file into the
problemtype folder. Here my line of code:

...
set fid [open /Programs/GidWin6.3.0b/problemtypes/FEM.gid/$projname.par w]
puts $fid [ ... ]
close $fid
...

For some reason it keeps appending "My current GiD project directory" at
the end of "My desired directory". Why? Is there a way to write a file
into a different directory? My current GiD project is at
d:\programs\GiDWin6.3.0b. Here is a screen capture of my error box.

Pls advice, thanks!
Tom

1) You can use the global variable GIDDEFAULT to locate the GiD directory
(a relative path is important if you move your problemtype to another machine)

2) Your variable projname contain the full path (d:\programs\GidWin6.3.0b\tests),
use file tail to obtain only the last filename (tests):

3) if projname contain blank spaces for example is not valid the order
open a/b/$projname w
because open expects two parameters, not more.

This is a corrected code:

global GIDDEFAULT
set filename [file join $GIDDEFAULT problemtypes FEM.gid [file tail $projname].par]
set fid [open $filename w]
if { !$fid } {
WarnWin "Error, file '$filename' cannot be open"
return
}
...

Hello,

You probably want something like:

set fid [open /Programs/GidWin6.3.0b/problemtypes/FEM.gid/[file tail
$projname].par w]

Probably, you do not want to use and absolute path for writing a file.
Doing so, you will not be able to use your
software in any other computer installation.

An additional trick that can be useful to someone is that, when a TCL
error window appears, you can press
middle mouse button over the window and more information will be displayed
about the error.

Hi GiD team
I'm now working also on "Error Estimation" and want
to use GiD generate (or add) the new mesh based upon
the Error estimation on that element (Triangular
element).

Please Look over on the attached file.


Best regards.

For this pourposes, it exists in GiD the concept of "mesh size assignation
by background mesh"
Your analysis calculate a new node or element desired size, based on the
error estimation, and write this information
in a "background mesh" file. GiD read this file and the new mesh is
generated based on this sizes.
Now it's possible to assign sizes using a background mesh of triangles or
tetrahedrons. The background mesh must cover all the domain (usually the
background mesh will be a previous mesh of the same model).

To load this "background mesh" file use the menu
Meshing-Assign Unstructured Sizes-Background Mesh...
If you load a background mesh, you can visualize the sizes (as points,
filled elemens or spheres) to detect bugs:
Meshing-Draw Sizes-BackgroundMesh

Background mesh file example:

BackgroundMesh V 1.0
MESH dimension 2 ElemType Triangle Nnode 3
Coordinates
1 5.61705 4.81504 0.00000
...
51 -5.64191 -1.53335 0.00000
end coordinates
Elements
1 24 16 26
2 16 10 14
...
76 34 31 28
end elements
DesiredSize Nodes
1 0.20
2 0.25
...
51 1.5
End DesiredSize
