Hexa mesh like Trelis

Recommended Posts

This is a mesh refinement from Trelis. Is it possible to do this in Hypermesh (auto or manual)? If so, how?

 

Thanks

Unfortunately I don't have this mesh because I don't have Trelis. Here's the link to the image I posted:

I wonder why HM doesn't have this ability for hexamesh (or it has and I'm missing it)!! This hexa mesh makes much more sense compare to the automated tetramesh in HM!

It's interesting your picture. But I would like to see inside of the mesh :)

 

Yup me too! I wish we had its file. It would be awesome to back track it and make it with HM ;)

Gonna ask around to see if anyone has/used Trelis and let you know if I got my hand on that mesh.

Quick question... in the original Trelis model, they used those elements that I enclosed with red lines (see screenshot 1) but in the mesh that I made in HM (screenshot 2), I didn't put them and still gave me a pretty nice transitional mesh (at least it passed all the element checks). Do you think those layers are necessary? I haven't run the model in any way and just wondering!

Hi,

 

Its good to keep one layer like this because drastically changing element size will lead in to poor results.So for better results keeping one layer like this is good.

Nice! I was also working on different alternatives... I got this:

Cool! Could you share the mesh?

Here's my test for 1-2 splitting

Thanks, here's mine. I made this using split (shift+F6) but the problem is in HM13 it only works one element at a time (in one direction each time). Hopefully in later versions of HM, they make it work for multiple elements.

Here's my script to create this splitted elements. My script can run for several elements but the script pays no attention to connectivity between elements.

Great! Thanks @Q.NGUYEN-DAI for sharing the script. I'm still learning tcl and was kinda struggling to do what you did this fast ;)

Any recommendation about learning tcl would be greatly appreciated!

There're a lot of tutorials about TCL on the net :)

Using Hyperworks without TCL is just 50% of software only :)
