Meshing Cylinder With Different Sizes Abaqus

Meshing Cylinder With Different Sizes Abaqus

Meshing Cylinder With Different Sizes Abaqus

Hello Guys,

I am wondering how to mesh the part in the picture. I want to have a precice mesh in the outer layer (size ~0.5), following a tet mesh to combine it to the inner part that should be a size of around ~2.5 like the global mesh. Since only the outer layer is involved in the contact, I want this to reduce the simulation time. Can somebody help me with that issue?
Thanks in advance.

RE: Meshing Cylinder With Different Sizes Abaqus

Since this object looks easily swept, I'd suggest you try using hex mesh and establish a boundary layer from the outer cylindrical surface. Save tet meshing for complex geometry, especially when solve time or element count are a concern.

RE: Meshing Cylinder With Different Sizes Abaqus

If you want a large difference in mesh densities without making transition regions, you can still use hex mesh but with each domain being a separate part connected with tie constraints to the other parts. Of course, the constraint should be possibly far from the areas of interest but it's a quick way to get such hex meshes.
