Hi GiD team,

See attached an imported lug.wrl file showing a 3D part structered mesh created in other solver platform. I have reproduced the geometry with same volume distrubution in GiD (lug.gid file also included), as it was the base for creating the structered mesh.

Question no1:
I could not generate an structered mesh of the 3D part within GiD, could you please tell me how it can be done.

Question no2:

Would it be possible to use the imported lug.wrl meshed file as the model wherein to run structural analysis with Ram series?, in other words, how to apply loads and constraints on meshed elements and not on surfaces as the standard way.

Thanks.

Hello Javier,

About the 1st question: the volumes 3 and 4 have 7 faces, it's possible to obtain a semi-structured mesh of prisms (than can be automatically splitted to tetrahedras), but not a structured one (it's necessary 6-faced volumes).
Can divide this volumes in two parts with exactly 6 faces.

About the 2nd question: If you directly import this VRML mesh, they are obtained triangles and some line elements (that probably must delete).
To analize as a solid you need a volume mesh, not only the boundary triangles.
If you want to analize as a collection of shells, you can directly apply conditions (loads, etc) to mesh entities instead to geometric entities, but in general this last option is unrecommended.

Regards
Enrique Escolano
