Hello all,
what's the easiest way to create a volume and assign different
materials to the volume and to the surfaces of which the volume is
made of? For example, if I create a rectangle surface and extrude it
to a cube and further create volume by Geometry - Create - Volume -
Search inside it, I'm able to assign different materials to the
surfaces and to the volume. But once I create the mesh and draw
materials, there's only the material assigned to the volume. So it
seems that "lower" entities inherit their material property from the
higher entities.
Are duplicate surfaces needed? Do the "contact volumes" have anything
to do with this problem? I've browsed through the manual, but didn't
find chapters addressing this problem. Thanks in advance.

When you generate the mesh of the volume, are only generated volumetric
(tetrahedra) elements, and inherit the volume material,
but are not generated surface elements (triangles). If you also want this
triangles, mush use: Meshing-Mesh criteria-Mesh-Surfaces
and select the desired surfaces. Then this triangles will have the material
of the source surface.

[GiDlist] regarding conectivity
The GiD local numeration of the element faces is:
Triangle: 12 23 31
Quadrilateral: 12 23 34 41
Tetrahedra: 123 243 341 421
Hexahedra: 1234 1485 1562 2673 3784 5876For example, in order to identify the second hexahedral face: 1484, you can see that is the only face
whith a "4" in the second location, then can use this fact to identify.
*if(Localnodes(2,int)==4)
FACE 1484
*endif
Localnodes return the local node number (1 to 8) of the face
Globalnodes return the global node number (the label node number) of the face
ElemsConec return the global node number of the element
You can also use:
*if(GlobalNodes(2,int)==ElemsConec(4,int))^
FACE 1484
*endif
But the first form is faster (avoid to call ElemsConec).

Dear Sir,
i am trying to find the face numbers of the 8 node solid elements. so one of my friend, he has used following command for that. and he is now not working here with me. so i can't ask it from him..
GlobalNodes(2,int)==ElemsConec(4,int)
please explain..what will show from..GlobalNodes(2,int)
and ElemsConec(4,int)
looking to hear from you soon..
