Is there any way to make a solid 3d mesh using 2 x 2d meshes (not as ends)?

Hello,

I imagine this must work in some way, but I can't find it on the Knowledge Base.

Please see here a picture that I created a 2d automesh on 2 different surfaces. And I'm trying to get HyperMesh to make a 3d mesh using these 2 surfaces. The surfaces have 1 common edge, so these are not 2 ends.

I really want a mesh like the end on the left in the picture (short-side), and I like how the long-side's elements line up with my 3d model shape.

When I use normal Solid Map mesh with the short-side as a source hint, it doesn't give the structure I want along the long-side since the top & bottom edge on the long-side are only allowed to have the same # of elements. As you can see, the log edge has 1 less element on the top vs bottom in the mesh that I want to create.

Thanks for any ideas how to get this to work.

I think it's possible. But you have to have "quad" mesh. See my picture

Hello,

In the aim to "extrude" your left side along the meshing, you must need to have only quad elements. Otherwise it is not possible to generate hexa elements.

To correct the number of elements and obtain only quad elements along the top and bottom, you can use the quick edit panel with the option adjust/set density.

Does it answer to your question ?

Thanks,

Richard

Hello Q.Nguyen-Dai,

Thank you for your feedback. Now, I see it.

I was thinkin the 2d tria on the long-side would become a set of tetras in 3d, but in reality it would become a row of pie-shaped wedges that are not within FEM. Sorry for my confusion.

I will see if I can control some other features (like biasing) to get more the long-side mesh target that I'm looking for.

Thanks again, Dominic

Hello Richard,

Thank you for your feedback. 

Originally, I tried the method that you were describing, but I achieved a bunch of elements on the long-side that were at an angle (because the opposite end of that 3d shape has a heavy angle on it). That's why I thought by using unequal 2d elements on the long-side would get the 3d mesh I was looking for.

My thought was the 2d tria on the long-side would become a set of tetras in 3d, but in reality it would become a row of pie-shaped wedges that are not within FEM. Sorry for my confusion.

I will see if I can control some other features (like biasing) to get more the long-side mesh target that I'm looking for. I may just need to split up the volume to achieve it.

Thanks again, Dominic
