Help meshing a complex part
Help meshing a complex part
(OP)
Hi all,
I'm meshing a lattice like solid structure but having nightmare meshing it. Would any kind hearted person have a look at it and help me mesh it? Automatic mesh is not possible, so I used Tet elements but elements are distorted. So best is to get Hex (C3D8) elements.
The cae file (Version 6.14) is here - https://www.dropbox.com/s/jw3mryb50k7kr8d/Mesh_pro...
Thanks!

Anyone? Help please!

As pointed out by people above, who know what they are talking about by the way, the geometry of your structure is better suited to tets.

Single beam, partitioned to achieve Hex elements -
Single beam, meshed with Hex elements -
Mirrored beam, Magenta colored region is not mesh-able to achieve Hex -
Again, Magenta colored region is not mesh-able to achieve Hex -
So guys, what is going on here? What should I do to get Hex elements on the Magenta colored region too? The new cae file is attached here - https://www.dropbox.com/s/452tdytz78lil3p/Mesh_pro...
Thanks in advance!

This way? But it still shows the Tet element as C3D4.

I'd try the hex elements and put up with the warning messages and check to see if your results look reasonable. You could also use a simple static test case to compare the results with a tet mesh before moving on to do the explicit analysis.

RE: Help meshing a complex part
I guess it would be better to use both Tet and Hex elements and see which one performs better. I am mirroring the single part to get a new part with 3 single parts, but unable to delete the top one (Double mirroring gives 4 parts). I have tried partitioning the top part and delete it but it does not work, it just deletes the mirrored region (top 2 parts in this case).
Could you please look into it?

Could you please upload the geometry file (in one of the Abaqus/CAE-friendly formats)? I tried the link provided above but the file seems to have disappeared.

RE: Help meshing a complex part
Is there anyway I can do this (Mirroring and deleting partition) in Part module only? Actually I don't want to achieve this through Assembly module.
