[GiDlist] structured mesh with contact elements in 3d

[escolano]

Try to download the last 7.5.3b beta version. The are solved some problems related with contact and structured mesh generation.

In other hand, I recommend to avoid the use of "GiD contacts" if they are not really necesaries.
A "GiD contact" is like a mesh restriction to create two meshes with a one-to-one nodes relation. Is this necessary for your analysis?

Hi Gid Team:



I'm using 7.2 trial version for a heat transfer problem in a plastic molding injection in 3d. I did the model in the same GID, because the .iges model can't be meshed with structured elements, the piece is a kind of ring, which is surrounded by a steel mold.



I want to do a structured mesh with brick elements, but my problem is when I created contacts volumes between the plastic and the mold, because when GID do the mesh, this has distortionated elements in the plastic, all completed outside the model, but in the mold and the contact's elements are OK . I tried to do the mesh without the contact elements and it works ok, the plastic and mold elements are good, the problem is only when the contact volumes are in the draw.
