Help meshing a complex part

[ShadowWarrior]

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 -

Thanks!

I tried downloading the file(s) but it seems to have disappeared. Anyway, why can't one-sixth of the geometry of one of these bars be meshed with linear bricks first? At least a few partitions in the bars seem unnecessary, by the way. Once one bar is meshed, it is a matter of playing with mirroring, merging nodes, etc. to get the final mesh of one bar. And then you repeat essentially the same procedure to get your final desired mesh.

Hi corus,

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?

Export the geometry to SolidWorks or CATIA or something, edit the geometry there and then import the edited geometry back in to CAE. In a recently faced situation, I realized that partition deletion in CAE isn't as intuitively simple as I was hoping it should be.

I tried SpaceClaim (my default CAD software), but meshing fails upon importing to ABAQUS.

Instance the single part a few times and then translate the copied parts and constrain them to match faces until you've built the full assembly.

I feel like this is a doable task for Abaqus/CAE. As I mentioned above, unless I am missing something, you could even instance 1/6th of the geometry of just ONE bar and then use the operations a bunch of us have been suggesting.

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.

Hi IceBreakerSours, The file has moved here -

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.
