Re: Why a NURBS surface always automatically rotates after being generated

The pink lines is a way of represent the surface in 'normal render'. The surface is represented drawing its lines 'a little' contracted to 'a center' Usually the surface lines are only the ones of its outer boundary or inner boundary of holes. By intersection or collapsing it is possible that finall...

Re: Assign multiple materials to an element (for different modules)

About materials (of a 'classic problemtype') You cannot assign two materials to a geometry or mesh entity. The entity object has a pointer, and only one, to a material what you can do is to define other kind of 'composed material' that could have for example to questions that store two, or more, mat...

Re: Volume

To use split to divide a volume, before the splitting collection of surfaces must be intersected with the volume (split must not do any intersection, and won't create or delete lines or points, only could create one or more splitted volumes and the original volume will be deleted on success) About t...

Re: question about “copy” command

In the copy window, unset the 'Collapse' checkbutton then new copies will be created, also if the new location is on the same location that other entities. And with the 'Multiple copies' entry you can create several copies. Note: new entities will be created on the same layer as the original entity,...

Re: Element type Hexahedra

I don't know the input requirements of SAFIR structural 3D. Maybe the volume mesh of hexahedra is not enough and it also require the boundary mesh of quadrilaterals, where the condition 'Global_Shell_Load' is attached. Then if the quadrilaterals are also generated the condition is applied to them, n...

Re: Mesh generation with a surface embedded

Maybe do you want to have a surface 'double' inside the volume (generating two faces, and two nodes, one by surface), then you can try to create a hole in the volume (a whole with zero depth). This is common to represent a crack, or a sail inside a volume of air. Then you can try to duplicate the su...

Re: number of contour elements in unstructured surfaces

We already didn't had time to debug your case

we have only time to confirm that we are able to repeat the problem.
we will study it and provide some solution (be able to mesh it or provide better information to allow the user locate and avoid it)

Re: error when launching the GID software

Which operating system? Windows, Linux? x32 or x64? The error message don't said what is the library that is trying to load when the error is raised, then is difficult to know what is the problem. Has ever started this exact GiD 13.0.4 version on this computer? If yes then try to reset all user pref...

Re: Mesh generation with a surface embedded

No, it is not possible to have a surface 'floating' inside a volume, it won't be included in the volume mesh. What is possible is to create a 'embedded mesh': the volume mesh is refined around its embedded surfaces, it won't be 'body-fitted' (the faces of the volume mesh doesn't match the surface tr...

Re: Element type Hexahedra

These conditions depends on the problemtype, not on GiD. (you have not specified what problemtype you are using) The warning message "Condition 'Global_Shell_Load' has flag 'on body elements' and maybe it needs flag 'on face elements' mean that probably the condition was designed to be applied ...
