GiD forum

Hi guys,

It's my first topic on the GiD forum. I try to handle this software, in the version 10.0, but I failed to mesh my model properly. My model is quite simple: it is a cube, defined by 8 points (4 apartments on the top face, a first layer, and 4 apartments on the bottom face, a second layer) as well as the 4 other faces, defined respectively in different layers.
When I mesh my model, on a corner the nodes are multiplied, do you know how to adjust this parameter and thus create "unique" nodes (see screenshot below) ?



Thank you in advance for your feedback and respectfully,

Victor Desloges

The mesh inherit the topology from its source geometry. What is 'connected' in geometry is connected in mesh.
If the geometric lines are sharing a single point, then you will obtain in the mesh a single node.

Is seems that creating your geometric model sometimes you are creating new points instead of select an old existing point (when selecting points <Ctrl>-a swap between expect a new point (3 real coordinates) or expect an existing point (1 integer id)

You can delete all duplicated points (close to a tolerance: the tolerance of Utilities->Preferences - Import - Tolerance) with the tool
Utilities->Collapse->Model

(probably the automatic tolerance will be enough for your case)
Then generate again the mesh

Hi escolano,

Thank's for your answer, it's now better !
