I have an L shaped slab that I try to mesh it with quadrilateral elements.
I have perfectly square elements of another element underneath it, and I
want to make my mesh matching each other. So, the L shaped 2d element needs
to be meshed with 2 ft by 2 ft square quadrilateral elements. When I mesh
it now, the elements turn to be curved. How can I have exactly square
elements on an L shape element which is not a rectangle but all lines are
parallel or perpendicular.
The solution may be to change some meshing properties, or maybe GiD is not
working properly. Please, could you send me the model in order to check it
and help you to reach the mesh you want? In case you want, please, send it
to my e-mail adress instead of the GiDList (abelcs at cimne.upc.edu).

I’m using GiD mesher/customization for my own FEM code. Former releases
of this code used their own preprocessor with a crappy 3D-block volume
geometry generator. It would be nice if GID could import those geometry
in a scriptig style (like GMSH does). I tried to do it via “Import GiD
mesh” and “Create Geometry from mesh” but this often fails on more
complex geometries.
Thanks for reply.

You can write a script to read this kind of files with Tcl/Tk language,
You can see as example the .tcl files of the GiD folder
\plugins\Import\pre
Have a look to the subfolder of cases of STAR-CD, EMA3D or UNV that are
relatively simple.
Note that each one of these ‘plugins’ add an menu to the Files-Import menu
to import the format thought the procedures defined in the .tcl file
You can see some information of GiD-Tcl special commands in GiD help -
Customization - Tcl/Tk extension
And there is a lot of documentation about standard Tcl/Tk scripting language
in Internet
