mesh with matching nodes with adjacent body

Recommended Posts

Hi,

 

In the attached model, I have 13 solid bodies assembled together. I was wondering what's the quickest method I could use to mesh each individual components in hex elements ensuring that the parts in contact have matching nodes.

 

Thank you

Your CAD is NOT complicated. It's possible to make a nice hex mesh.

What do you mean "the quickest method"? Something like "one-click" meshing?

I tried boolean but I end up with non mappable surfaces which I don’t know how to get rid of which I don’t know how to get rid of. Not one click meshing ;) 

Do you have a method please?

I have done a lot of splitting with manual editing of the nodes but my aspect ratio is not good (i want them to be less than 3) and the jacobian also (i want them to be > 0.7).

Any ideas how to improve this please?

Hi dilen,

 

You can improve the mesh quality still more as shown below. You need to create a duplicate component and move each solid into that and then mesh the solids separately.

Please refer to below tutorial, you'll understand properly.
