if do you have a volume off course the volume is meshed.
If you don't want volumes simple delete them if they exists.

Off course you can do this in multiple ways. By your message you are using a 'classical' problemtype, with .cnd, .prb, .bas, ... The modern approach is to use a 'customLib' problemtype, where the data is shown in a tree widget, defined with a .xml file, and the data is usually written with a Tcl pro...

These characteristics depend on the type of problem used for the simulation, not GiD The boundary conditions and its meaning is defined by the problemtype, and from GiD you assign them to the model. Probably you are using some structural code with 'solid elements', and the 3 degrees of freedom are t...

Instead of do 1.Unstructured mesh>assign size to surface>> 0.006mm 2.Select element type>>triangle 3.Generate mesh you can simply do 1.Generate mesh, with general mesh size=0.006 units (by default surface mesh is triangles, and the general size is used when there is not any specific assigned entity ...

It seems that your geometric model doesn't has a volume, but only surfaces, and these surfaces are not sharing the lines and probably also the points. You must do collapse, with a tolerance, as you pointed (entities close than this tolerance must be joined) The automatic tolerance value is usually g...

Officially, GiD licences have an unlimited duration for one specific computer. Changes of licence to a different computer are exceptionally allowed only within the first year after purchasing the licence. In any case, contact us by e-mail at gid@cimne.upc.edu explaining your case and providing infor...

it seems an error or limitation of version 12. With current GiD 14 you can read your multiple meshes+results in postprocess with Files->Merge... (could use merge because your nodes and elements that have unique unrepeated id) It doesn't raise any error, but the isolated node is not showed in the fin...

Are you sure that deleting the user preferences is not solving the problem? Delete the whole folder C:\Users\<your_username>\AppData\Roaming\GiD and then start GiD, it will use the default values Don't worry about the message "problems checking upgrades".. It simply mean that from your net...

Sorry, I don't understand your question. Which problemtype are you using? Where and how is created/showed this graph? It is the graph showing the 'table' values of a question field in preprocess, or it is a graph of some result in postprocess? In the first case, can add a new row of the table pressi...

Dependencies are very limited, I think that this double dependency is not possible (and maybe for a final user is also confusing) Reconsider if you can reorder your data and use a single dependency e.g. the first dependency A could hide or disable a tab (title) where other questions B, C are shown, ...
