[GiDlist] Difficulties with mesh generation

[Timon Rabczuk]

Dear GID team

I am trying to mesh a complicated tree structure-the bronchial tree of
the human lung- with GID and I am having severe difficulties to generate
the mesh. I have the bronchial tree as stl-file. Since it is not
possible to mesh the entire structure with GID, I split the tree in
several parts. I was successful in meshing every sinlge part of the
tree. However, when putting the parts together into one model and
merging (with collapse surfaces) the tree, GID crashes with the
segmentation fault. Do you have any suggestions what to do?
Thanks a lot for your help!
Best!
Timon
P.S. If it is helpful, I can send also a sample.

Probably GiD crash when collapsing "surfmesh" entities, because is an unsual
entity.
Can try to delete the parts to be shared between parts, and create true
NURBS surfaces from it's boundaries.

In general , try to manually change as "surfmeshes" as possible by true
NURBS.

If you don't be able to generate this mesh, send us the model (compressed)
directly to escolano at cimne.upc.edu

Hello GiD-Team,

i have one proposal for GiD in post-processing mode.

When using the "View Results" window, you can select to view a deformed
mesh or view results on this deformed mesh.

But if i change the result step the displayed result gets out of sync.

The question is if there is a possibility to syncronize the result step
in the "View Results" and in the "Main Mesh" tab of the "View Results"
window to get proper results.

Regards

Martin

O.k., noted.

But in the mean time, what you can do is select the c.fill & deformation in
the 'View results' window, and in the Animation window use the slide bar to
change the step. Then you'll get both, c.fill & deformation sinchronized in
the same step.
