Hi all,
I am trying ot excetute the Normal models solution using Optistruct and I get this error:
-------------------------
Duplicate SPOINT ID 365 - it is used on GRID card.
---------------------------
I went through the forum and found that renumbering migt help. I renumbered all the nodes, bit it still showed the same error.
Looking into the .FEM file, I found the node in the GRID
The node ID doesnt seeme to be duplicated.
Saddly I cannot share the file, since it is under the NDA.
All the help would be much appretiated.
Regards,
Uroš
