3D Mesh of a cartilage

Marvin_20618

Hello,

i need some help: i want to mesh the cartilage with hexaeders. There should be at least 5 elements above the thickness. I tried it multiple times, but i did not succeed. I'm thankful for every idea!

meshing with hexa elements usually is not so easy for non-uniform parts.

Maybe you could thr some CFD meshing tools which can generate the boundary layer with hexas. (you can ask it to generate N layers of well controlled mesh in the outside, and the inside can be tetras.)

 

But may I sk why do you specifically need an hexa mesh here? Couldn't it be some good tetras?

Just for curiosity.

Thanks for your reply! 

I'm using hexas because the cartilage is very soft. I think the tetras are tending to react more stiff on load. Additionally i did a convergence study with hexas but with a simple part.

Maybe i should overthink the strategy and use tetras ...

I already did a lot of meshing but always with more simple parts where you can use a 2D mesh and drag it or solid mesh for thin solids. Can you please roughly describe the steps for meshing it? I did not find any tutorials or something helpful..
