Salome cannot detect duplicate nodes under NODE CONTROLS yet they exist

Use of the platform
1

Hello,

I have tried opening some old unv file which I converted to med.

In Salome when I use NODE CONTROL> Duble nodes, It is shown to be zero.

Yet there are overlapping nodes between ‘targe’ and ‘conta’ groups.

You can check with mesh info. Each overlapping element has different node connectivity. Also these groups are used with code_aster run in DEF_CONTACT(which will give error if both master and slave faces have same node support). The run works.

increase the tolerance, which is set to 1e-7 by default as one can read it from the configuration file here.

To adjust this constraint interactively in the GUI, activate the SMESH module and navigate to: File → Preferences → General → Double nodes tolerance

A value of 5e-6 or 1e-5 should work.

Attached is a script to cross-check the results against the output of Controls → Nodes Controls → Double nodes.
