strange, it does not work for your geometry ...


square axle compound_BHA.FCStd

By the way, you can see from the deformation shape of the face that external nodes are connected, but internal not. :shock:

We should may be try gmsh mailing list!

I may give your geometry another try on the weekend.

Where is this smily which bangs his head on a wall ...
You cant imagine how often I use the FEM-WB.
God bless you Bernd.

this is what you would like to have? Am I right?


notconnected.FCStd

I tried and indeed in this example the elements and nodes perfectly align and are duplicated. However, in my square axle example this is not the case

I am taking a different approach now. To make sure twin faces and nodes line up I start from compsolid and with my macro duplicate mesh nodes and reconnect mesh volumes. I got it to work for the stacked blocks, so the proof of concept is there.

wow cool, can't wait to see this code.

BTW: would be a great addition to femmesh.meshtools module ...
