Dear Coreform-Cubit community
I am trying to generate an all-hex mesh for the attached CAD model. I was able to mesh it successfully using Sculpt, but I am posting here to ask for opinions and advice from others.

I would like to learn how to decompose the model using webcuts and then generate a hex mesh using sweep, map, or submap schemes. I have been trying for two weeks, but I have not been able to make it work. I think this is because there is a very large difference in size between the volumes, and because Volume 3 has an irregular shape.

Ideally, I would like Volume 3 to have the finest mesh and Volume 1 to have the coarsest mesh possible. If that is difficult, having a uniform element size for all elements would also be acceptable.

I would greatly appreciate any advice or suggestions.

Sincerely
WON

Hello @Yeongseon,
do you happen to have the geometry also in ACIS format? Currently you are using the facet geometry engine. Webcuts for facet geometry is still in development and also not all options are supported.

It is best to use cubit with the acis kernel. So a sat or step file would be good.

Did you create the geometry within cubit? If yes, do you still have the journal for it?

Hello @Norbert_Hofbauer
I appreciate your advice!

Yes I did. i will attach the journal file!
