Converting multiple 2d surface meshes to one 3d mesh
Altair EmployeeThis may have been asked before, but I could not find a solution. I have just recently started using HyperWorks and am trying to create a 3d mesh from multiple 2d meshes. So I am wondering how I should go about this, or if it is even possible with this software. Here are my three surfaces that i made, and I would like to use these to create a 3d mesh but am not sure how. I am aware of the drag feature if I were to simply use 1 of the surface meshes but that's not quite what I want.

Hi Brandon,
Did you try with element offset option, with which user can create solid layers. Please go through Elem Offset Panel in Help Menu

Hello,
I think is not possible to create hexa mesh on this solid.
I have separated the solid in many solids.
I have tried to manually mesh the transition solids and there are few areas that make this process impossible. (see attached).
If someone create this mesh, will be very interesting to find that this is possible.

You should have tried 2d transition like attached screenshot.

Yes I see what you mean now, I will try to do a different transition configuration and will keep this in mind.

That would work if I only wanted two faces, but the third one I want included as well, so it becomes difficult in that regard.
edit: Oh, i see what you did now, yes that is something I will look into, thanks!

'I would like to mesh one sheet thickness of 1 mm, length 400 mm and width 300 mm, in the same way as shown in the attachment. In the direction of the width '300 mm', 1 element becomes 4 elements at the passage of a 'transition' zone, then the 4 elements become 16 elements at the passage of a second transition zone. Can you help me? I use Abaqus. Thank you.'<?xml version="1.0" encoding="UTF-8"?>

Hi aberbac1
You can check this forum post and video on mesh transistion.
I hope this will help you

Hi,
This is an older topic we talked about. You can refer
https://community.altair.com/community?id=community_question&sys_id=e33648761b2bd0908017dc61ec4bcbb7
this is 1 to 3 elems. you can find more patterns in above topic.

Tinh, that mesh only has transitions in two directions. You can't use the same technique on Brandon's model.
Brandon, it is (geometrically) possible to transition in all three directions with hexahedral elements only. But you will need to use a butterfly at the corners so that the transition kind of wraps around the corners. I don't know how to do this in HyperMesh, though.

I haven't updated this topic since when I first asked but I figured this out quite awhile ago. Here is how I did the three directions if anyone is interested.
