Hi,

I would like to know how to mesh a component more and more thinner with a growth rate like on this figure. Can anyone help me to find out how to do it please ?

It for a rectangle (2D component). 

Thanks, regards,

Charlotte

Hello,

 

You can do this in a couple of ways.

 

Firstly, you can mesh the entire component with a similar element size and then increase the density of the mesh as you go along the edge.

OR

 

You can split the surface in multiple and mesh separately each split according to your requirement.

 

Thank you

Hi,

Ok thank you for your reply.

It works but I didn't specify that I wanted only squared elements. And when I put a different density to opposite side of the rectangle, triangle  elements appears.

So I use the same density on opposite sides but introduce a biasing. It works for an intensity of 1 or -1, but when I put more than an intensity of 1 (because I would like to have smaler elements in a angle), there are trangles again.

(I used the minimu size of element (0.05) when i firstly mesh the component).

Would you know how to keep squared elements and have smaller elements?

Regards,

Charlotte

Don't forget : if you add more meshing contraintes, the quality will decreased. So you have to accept some compromises.

C'est la vie :-)

Hi everyone,

Yes it's true I don't get only squared even if I controle the shape of the elements. but thanks for replying. 

Ahah I understand, it wouldn't be physical anymore, if they were only squares. J'ai trouvé un compromis :)

Hey, triangular elements are NOT "bad" elements :-)

Bonne continuation!
