How to mesh redesigned section without remeshing entire models

Mesh1

Hello ,

I am using Hypermesh with Abaqus solver. I have a simple assembly A, and B.

The design is changing, with some small modifications. (i.e., add rib, remove rib, thicken, trim etc.)

Is there a way to only remesh the new features rather then remeshing the entire part ?

Thank you

Of course you can! Juste split your current mesh into two parties:

unmodified mesh
modified mesh

The modified mesh can be delete. Do the same split for your new geometry. Make new mesh by keeping the same element density as old mesh. Finally, don't forget to do nodes equivalent between old & new mesh and you got updated mesh.

Hi Nguyen,

Sorry, I am very new to FEA/Hypermesh.

I think I may be on the right track. The brown mesh is the unmodified. The grey surface is the new modification. Which I will mesh.

How do I delete the brown (unmodified mesh) and keep a "nice pattern" The way I am deleting now is jagged. Is there a slip long line or feature ?

Maybe you increase the splitting area to get a "simple" form.

For similary case, some times I have to make manual mesh, element by element.

Hello,

You could try fuse as well
