Finding unintended cracks in mesh
I was astonished that there was an unintentional "crack" in the mesh in this discussion.
The mesh had Node Merge applied in the Mesh Edit branch so I expected that the nodes were merged, but clearly they were not. This was revealed only after the solution was examined carefully with the deformation contour plot.
How can these unintentional "cracks" in the mesh be found before the solver starts on them?
SIEMENS NX has a way to display the "free" edges of the mesh. Here is a mesh before the node merge.
Here is the display just after the merge node command. It is easy to see before the solver starts that this mesh has a crack.
Here is the "free edge" display in case you missed the display above. It is easy to see before the solver starts that this mesh has a crack.
Below is the "free edge" display after loosening the Node Merge tolerance. Now there is no crack.
How can I see if there are unintentional "cracks" in an ANSYS mesh before the solver works on it?
