Hello,

If I have a rectangular surface that represent the domain and inside that
surface there is a line that represent an antenna and then mesh them using
tetrahedral mesh, the mesh file will have two blocks the first one
represent the tetrahedral elements for the surface and the second one
represent the line. The problem is that the nodes that represent the line
elements are not aligned to the nodes that represent the tetrahedral
elements. is there a way to force the tetrahedral mesh to mesh the two
objects in a way that the line and the surface share the same nodes.

Your line must be contained in the some surface boundary of your volume:
Must split some surface using this line, and also is needed to force to mesh this line
(Meshing-Mesh Criteria-Mesh-Line) to force to generate also line elements, instead of only tetrahedrals.

Hello,

I can't have boundary lines among different materials
when I select "View Style"-"Body bound" in post-processing.
In other words, there is no difference between "Body" and "Body
bound"...
("Body lines" is ok)

This might be a problem just on my video card
since I used to have the boundary lines before.

Hello,

You need to subdivide your geometry so as:

- The line that represents the antenna is boundary of one or more of
the surfaces.
- That surfaces are boundary of the volume.

This is not a graphic card problem.

If you generate a mesh in preprocess, then when you change to postprocess
the elements are separated in sets by element layer (default) or by element
material.

Can set the variable PropertyToPost whith the value "Material" or "Layer" to
change this default
(escape escape escape Utilities Variables PropertyToPost Material )

Must separate in preprocess the source surfaces in different layers, or set
PropertyToPost to Material
If the elements are located in different sets, then the sets-interface is
draw also as boundary.

Thanks, Enrique.

I have tested both modes ("Material" and "Layer") but couldn't the
boundary lines at all. Even if I have one material or layer, I couldn't
get the lines on the exterior boundary of the object.

I newly installed GiD on another PC. Then, the boundary lines are drawn
properly.

It seems like the problem occurs just on my laptop...
Is there any way to initialize GiD???

Try to start GiD without OpenGL hardware acceleration (Start GiD safe mode, and select "software OpenGL")

See this FAQ: http://www.gidhome.com/support/faq_8.subst (I try to open GiD by the first time on MS Windows and it crashes)
