meshing 3D: surface is not closed

[Laura]

Hi,

I'm creating 3D mesh from image, with 3 materials. But, when I generate surface mesh and test closedness, Aviso found that surface is not closed.
What does it mean ? What is it necessary to do ? :confused:

Thank you for your answers. :)

We saw this a couple of times and this may be dre to some precision issue and in these cases the surface is actually closed and the Tetragen module should work fine, unless there are actual holes in your surface. If you want I can have a look at this. Upload your labelField and Surface in one Laura.zip file to ftp://mc3dviz.com/incoming.
