Meshing 3D with different layer sizes

[Anonymous]

Hello everyone,

is it possible to create a mesh in 3D where I can get different element sizes over the thickness?

Which means e.g., that the core area has a fine mesh and going to the wall, there will be a bigger gap between the nodes.

Thank's for your help and BR!!

Hi,

in 3D mesh generation you have the

Tetra Advanced tab

and Node biasing through thickness.

This setting should do what you ask for.

From on-line help:

Bias ratio
The ratio of the thickness of an inner layer vs that of an adjacent outer layer.

For example, if the ratio is greater than 1, outer layers (close to the surface) will be thinner, and inner ones will be thicker.
Consequently, the node density near the part's surface will be higher than that near the center.

Conversely, if the ratio is less than 1, inner layers will be thinner than outer layers and the node density near the center of the part will be higher than near the surface.

Enter a number between 0.5 and 2.

Give it a try.

Hope this helps.

Regards,
Berndt
