external nodes
(OP)
Hi!
I have a modeling question. I have an arbitrary figure created only with nodes and without elements. How can I choose the external nodes?
Thanks.

RE: external nodes
In my opinion, without programming, you cannot solve it. I read on Internet about a algorithm on 2d who can find the external nodes of o nodes cloud. Should work in 3d too. But I don't remember how is the name of this algorithm...

RE: external nodes
yep, but I suspect the O.P. wanted to refer to convex domains (otherwise there is no algorythmic possibility to determine the "external" nodes). For convex domains I remember that there is an algorythm for that. Sorry I don't remember where to find it...
