Meshing complex STL file

Hi Andreabb

set minimum tet collapse value and generate the mesh 

Hi Pooja S,

how can i do this? Do you mean the collapse of the nodes?

Hi Andreabb

Tet collapse defines the height of tetra elements ,  can be set as shown in the below image 

<?xml version="1.0" encoding="UTF-8"?>

Unfortunately, this way creates uniform mesh (tetra elements similar in dimension, i try with 0.01 minimum tet collapse) and collapse the details of the lattice region. Do you know other solutions?

Hi Andreabb

Please share the model 

Hi Andreabb

Attached the video clip  for your reference , it might help you 

To create tet elements click on 3D> tetramesh

Hi Pooja S,

My structure is more complex. I create two different mesh with 'shrink wrap' and this is a part of my model. There are two components: lattice part (that needs precise mesh) and massive part (that needs rought mesh). How  can i merge the two part?

Hi Andreabb

the best is  do the  2D mesh on the outer surface with tria elements with good quality and then  create the solid mesh 

for solid mesh refer the pdf

Thanks Pooja S,

I make the tria-mesh on the surfaces(2d) but  after this the solid mesh (tetramesh) isn't available because 'the mesh is not enclosed'.

Just identify not enclosed zones and make manual correction.

Unfortunatley there are a lot of this not enclosed zones and I can't adjust these.
