[Nek5000-users] Mesh merging - no curved side data left

[nek5000-users at lists.mcs.anl.gov]

Dear all,

I tried to merge a cylinder with a rectangular hole, with a rectangular
box. After merging them, the curved side data in the cylinder is lost. Is
there a way to preserve the curvature?

Also, I got error with mesh tolerance. Anyone knows what the error means?
