[GiDlist] GiD crash in meshing

[Andrea Calaon]

Hi GiD team,
I am experiencing some difficulties with GiD 7.5.8b (Windows
2000). When I try to mesh with quadrilaterals structured a
quadrilateral surface that has two sided formed by a line and
an arc GiD crashes. The model with the simple surface is
appended. I tried to collapse and repair but nothing changed.
If I try to Generate the mesh I have a crash.

Best Regards
Andrea

Hi Andrea,

you seem to have the same problem as i did.

If creating too small geometries GiD has problems in handling these,
starting from within the geometry generation and reaching up to the
creation of the mesh.

As a workaround just create a scaled model with factor 100 or more.
Another workaround is creating a point with in the gravity center of the
model and scaling the model by factor 100 or more.

After doing this the mesh generation worked.

Bye Martin

Thanks Martin,
unfortunately changing the units in this model is not that
"easy" because is for a sort of benchmark for crack
propagation ...
I managed to have the mesh from GiD 7.2; I believe that
version of the mesher is not so scale sensitive.

Best Regards
Andrea

Hi Andrea and Martin,

I'm Abel Coll (a GiD developer). With the last version of GiD (that is not
available yet) this problem is solved.
Mesh can be reached without any problem, as you see in the attached image.
GiD crashes in version 7.5.8b for some bug that have been corrected
recently.
It's not necessary to scale the model. Maybe this week (or at last next
week) will be available next beta version, with this problem solved.

Regards

ABEL
