Locked node numbers on edges are changed by ICEM
 

Hello everyone, I am running into a bit of a problem and I wanted to ask, if someone here knows a solution.

I am trying to 3D hexa mesh the geometry of a furnace with a dummy load. I have got around 30 blocks or so and the edges don't all line up. E.g. I have 5 edges which have the same number of nodes combined as 1-3 other edges combined further down the x-axis. What I want to have is a symmetric mesh, so I enabled "Nodes/Parameters locked" on 4 of the 5 edges (the outer ones) in order to force ICEM to change the number of nodes on the edge that isn't locked (the one that is split by the symmetry axis) if I change something on the 3 edges. But even though the number of nodes is locked ICEM sometimes changes it instead of the number on the "free" edge. Is there maybe any special sequence I need to follow when I set the parameters on the edges, e.g. set the "free" edge last? Or is there any "real hard lock" feature where ICEM can't change the node number on its own anymore?

I hope the image below can help in understanding my problem.

Hello there,
Have you solved your problem with floating nodes number? I have the same issue.

Best regards

Imagine this as having two edges in parallel. Edge One which is longer and the other one (edge2 ) which is same length but divided into 3 pieces in length ratio 0.1:0.9:0.1.

Let's say have 30 nodes on edge 1 (longer and splits).
And on edge 2 you have nodes in this ratio of 5:25:5. That's 5 nodes extra to the other parallel edge. (which is not permissible in ICEM or structured meshing).

So even if you lock parameters the program is going to have change one of the edges

It is one to one correspondence, how you can lock nodes on one edge and change on other?
