[GiDlist] Problems with unstructured meshes

Postby Johane Bracamonte » Mon Sep 25, 2006 11:33 pm

Hello all,

I am modelling a 90º elbow with straight pipe attached at each end of the
elbow for a BEM study. The straight pipe is meshed with a structured
quadrilateral and quadratic mesh, and i want the surface mesh of the elbow
to be unstructured quadrilateral and quadratic. The problem is that some
elements of the unstructured mesh at the boundary with the structured mesh
are wrong, a node of the outer face of the elbow is at the inner face, i
have attached the image to explain myself better.
Can anyone tell me how to solve this problem?
Thanks and regards

[GiDlist] Problems with unstructured meshes

Hi Johane,



I’m Abel Coll from the GiD Team. I seems to be a bug in the code that
produces this irregular elements.

Which version of GiD are you using? Can you send me the model to be able to
fix the bug?



Thank you for notifying us this behaviour.



ABEL
