Line element refinement

kennethfugate

When using the "x3 (1D/2D Elements Only)" refinement, I've noticed that it spills over onto the adjacent elements. I've uploaded an example where I select the diagonal line element and do a refine x3. Notice the adjacent horizontal and vertical elements are also split instead of only refining the selected element.

Thanks for bringing this up. In some cases, that's the correct behavior, such as when the line elements are laid along the edges of shells, but not here where they're simply joined end-to-end. I'm not sure if I can fix it without creating more strange edge cases but I'll see.

A workaround is to use Mesh tools -> Disconnect elements before refining then merge them back afterwards.
