change node label

Hi
I want to change the number of a node in the GID software. Is it possible to guide me step-by-step?

Manually edit the GiD mesh in not the right way to use our program.
The appropriated way is to edit the geometry and apply all simulation data to this geometry, and automatically generate the mesh.

About node numbering, GiD has a variable ‘RenumberMethod’ that allow set different ‘renumbering’ algorithms. (usually to try do have a low ‘band width’ for direct solvers). See GiD help on Utilities->Renumber.

Usually you could have millions of nodes, unable to be set manually.
I understand that probably want to repeat some very small academic case, and do you want to have full control of the nodes/elements ids

Off course you could to tricks to change the numeration, like export as ‘ASCII project…’ and edit with a text editor the mesh file and re-open the project, or others…
