Rules of Node Numbering in CAE Mesh
Rules of Node Numbering in CAE Mesh
(OP)
Hi,
I've established a model in CAE and modified its dimension without changing the meshing properties(exact same type and number of elements and nodes). The only thing I expect to change is the coordinate of each node. However, I found the number has also been changed for each node. I know there must be some rules beneath the meshing algorithm but does anybody know the exact reason and how to make the numbering consistent?
Thanks.

Thanks for your reply. You are right that linking the setting to the model geometry itself will make renumbering not necessary. However, I'm using the inp file to run parametric study on the model geometry. The reason that I avoid using CAE is that some properties are not able to define there. To make it work, I modified the geometry in CAE and copy the generated mesh information into the inp file (there might be some better ways to do it). The problem is that I found the numbering of nodes in each modified geometry is not consistent. I'm quite confused about why this would happen...
