Duplicate grid error
Duplicate grid error
(OP)
Hi
I am working on a Femap model and trying to mesh with little coarse elements because of my computer memory limitations. I am basically deleting the old mesh and redefining the new and I am getting this error message
"DUPLICATE GRID POINT REFERENCE NOT PERMITTED FOR ELEMENT TYPE"
and the warnings like
"UNABLE TO DEFINE ELEMENT ORIENTATION FOR TRI ELEMENT ---- "
Any suggessions to get rid of these errors and warnings and work with sufficient memory I have ...

RE: Duplicate grid error
neema1984,
I would say that you are using twice the same node to define a triangular element. Just a guess based on what you posted.

I am actually meshing automatically just by controlling the size. Not defining manually.
What can be the best way to mesh it ? .. manually for each surface ?

Patran is a nightmare for being "unintuitive" - as are the rest.
My guess, it has equivelenced nodes and not cared that it is a ctria or you have managed to create an element along a line, it can happen if you are not careful when meshing or fixing manually.
My advice, delete the offending elements by hand or by scripts.
Or remesh.
