smoothsurf works incorrectly

[StudentFS2]

Hi!
smoothsurf clearly work incorrectly on my geometry. I attach geometry here
files.zip
load('el.mat')
load('no.mat')
plotmesh(no,el)
sz=size(no);
no=smoothsurf(no,[],meshconn(el,sz(1)),1);
plotmesh(no,el)
clearly puts something inside of one of the channels.
Best regards

@StudentFS2, again, sorry for not reading about this report until now.

I loaded your data, it looks like the garbled nodes/elements are there already before smoothsurf.

the presence of these garbled nodes is caused by a upstream CGAL bug I explained in #54 - the meshing process failed to complete before reaching the maximum node limit (type length(no), you can see it is 40,000, which is the default maximum node limit of vol2surf.)

because of this, I am closing this ticket because smoothsurf works as expected. it was vol2surf (specifically, cgalsurf) that failed to create a valid mesh.
