[Gmsh] R: Re: Runtime crash and Display nodedata with few nodes

[corra85 at tiscali.it]

Dear Prof. Geuzaine,
Thank you for your quick answer. I amended the 
file as you suggested and now it works fine when opening the file. The 
second problem I addressed, though, is not solved. My NodeData are 
defined on a smaller node set than the total, and I cannot see it 
anyway. I tried also with the "view5.msh" file in documentation:  if I 
define a nodedata set for a smaller set (let say, removing one node 
data) than the total number of nodes, I cannot see it. I attached the 
file for clarity.
Thank you in advance,
Corrado

There is no limit. The problem here is that 
your vertex tags (e.g. 11010101, 41040419, ...) span a very large 
interval. This is not an issue for the actual mesh, but it is for the 
NodeData. For efficiency reasons, NodeDatas use directly vectors (not 
maps or hash maps) indexed with the vertex tags. With your tagging this 
leads to the creation of huge vectors--mostly empty.

Simply tag your 
vertices with consecutive tags starting at 1 and you will be fine.

I 
will add a note about this in the documentation.
