[GiDlist] running time for meshing unstructured volumes

Postby Isabel Gil » Fri Feb 03, 2006 1:52 pm

Hello to everybody!

On december of 2005 I got the latest beta version so that I could use
the SemiStructured option and mesh a volume with unstructured hexahedral
elements (structured in one direction and unstructured by lines in the
master and slave surfaces).

The problem is the time the program takes to mesh the volume, indeed,
sometimes it doesn't get to mesh it at all. I don't know if I am doing
something wrong.

I don't know whether the number of elements may be the problem: If I
want to create 22050 hexahedral elements it takes long but it does it,
but if I want to create 33075 hexahedral elements the program runs but
never finishes.

I would be really grateful for your help or for some advice.
Best regards
Isa

Hello, Isa,

I'm Abel Coll (GiD developer). Could you send us the model you are trying to
mesh and the
meshing preferences you have to look for the problem, please?

Regards,

ABEL

[GiDlist] running time for meshing unstructured volumes

Postby Isabel Gil » Thu Feb 09, 2006 1:22 pm

Hello Abell & co.

Sorry for not having written before, I have been abroad.
I am attaching my model and, as I said before, I would like to create
the following mesh:
* Element type would be hexahedra.
* The two surfaces on plane xy, unstructured lines of an element size of
0.0005.
* The number of divisions in structured direction would be 3.

I'm looking forward to hearing from you, best regards!

[GiDlist] running time for meshing unstructured volumes

Postby abelcs » Fri Feb 10, 2006 3:21 pm

Hello,

The problem is related with the memory that GiD spends using semi-structured
mesher within hexaedra. I will look for a solution and as soon as it will be
solved it will be available in the next beta version.

Thank you for notifying us this behaviour,

best regards,

ABEL

Hello, Isa,

The problem with the semi-structured mesh is solved. Now your model can be
meshed without problems of excess time or too much memory allocated. In the
next beta version it will be available to all the users.

Thanks again for notifying us this behaivour.

Regards,

ABEL COLL

Postby Isabel Gil » Thu Feb 16, 2006 12:22 pm

Hello Abel,

Thank-you for solving the problem. I am really grateful.

Then, I will have to download the new beta version, won't I? (what I
have now is the 7.7.2b version)
The problem is that I have used the three free downloads and I won't be
able to test my model.
Would it be possible to obtain once more a free password?
I look forward to hearing from you.

Best regards,
Isa

Postby abelcs » Fri Feb 17, 2006 10:35 am

Hello, Isa,

You can download beta versions as many times as you want for free. There's
no limitation for the number of dowlnoads. The only limitation is in the
password, that have a limitation of time.
On the other side, the password you have can be used in all 7.xxx versions.
