EDIT MESH: Edit disconnected mesh
Hello there!
I'm currently working on my Bachelor's Final Project. I thought it would be very easy to mesh it out and run my test, but I've found the following problem: some disconnections in my 3D mesh (Figure1).
I've solved it by remeshing but I would like to know if there is a more efficient way to do it. How can I edit the mesh to fix that disconnection?
Thank you so much!

There is not much to really do to fix a disconnected 3d hex mesh efficiently.
If the mesh is disconnected, but has the correct number of nodes simply equivalence. I usually start with a very low tolerance and bump up making sure to keep it less than the smallest element size.
If the nodes do not match, you might need to recreate a new patch using the Hex tool
Best is to make sure the hex mesh is properly created in the beginning.

Hi Jason!
Thank you so much for your help.
I tried your solution but 0 nodes found or were equivalenced.
A bit more info: I meshed the helmet using Solid Map after divided it in smaller solids to make it mappable. Then, that disconnections appeared.
Any ideas?
Thans again!
