vtp connectivity node table

[Aloma Blanch]

Dear All,
I am trying to extract the connectivity table of a mesh surface .vtp file in the following format,
element_number face_ID node1 node2 node3 as it used to be on files .ebc.

I tried to use David Parker code (https://github.com/ktbolt/vtk/tree/mast ... esh/python) as a starting point, but I could not get the nodal information.

In this link (https://marq-my.sharepoint.com/:f:/g/pe ... Q?e=K9a8b8) I uploaded the files I am using, just in case.

Thank you for your help.

Hi Aloma,

I had a brief look at your code. For printing the coordinates, I see

Code: Select all

format(i, node_id, x, y, x)

Should that be

Code: Select all

format(i, node_id, x, y, z)

If that's not the problem, let us know how exactly the code failed.

Thank you Martin,
I did not see that error.
But, I'm having another problem, in the code I attached I'm extracting the node information, in the following order:
element_node, node_id, x, y, z
Node 38165 ID: 56153 Coords: 1.05515 6.65914 6.42562

But, what I am trying to extract is the element_number, face_ID, node1, node2, node3 as it used to be saved on the old .ebc files.
I'm lost in what vtp Class Reference I need to use to achieve that.

Thank you for your help.

Dear All,
I am struggling to find a solution and I was wondering if it is possible at all.

Thanks for your help.

Hi Aloma,

I modified the print_mesh.py script here https://github.com/ktbolt/vtk/tree/mast ... esh/python to work with .vtu and .vtp files. Try it out and let me know if it solves your problem.

Cheers,
Dave

Thank you so much Dave,
It solves exactly the problem that I have.
