Can 2D and 3D mesh exist in the same model at the same time?

Altair Forum User

Hi,

 

I want to mesh an object built from CAD software.

 

The question is: Can I make 3d tetra mesh on one half of the object, and 2d automesh on the other side ?

 

Ultimately, I want to analyse the mesh by using FEM software ABAQUS.

 

But I haven't heard such a thing that the 2D and 3D mesh can be connected to each other, so I am asking here... 

 

Thanks.

Yes, it's possible, depending to your objective.

 

Because 2D mesh can not modelize all geometrical details, for example the chamfer, fillet,... we have to use 3D mesh in order to catch good and realistic results.

 

By mixing two types of meshing, the important question is how to assembly them? There're many technique to do that, but the most important thing to remember: never make such 'assembly' in critical zone (high level of stress, concentration,...)

 

HTH,
