[Gmsh] Converting 2d to 3d mesh

[DILASSER Guillaume]

Hi,



It looks like you are trying to turn an imported STL 2D shell inside Gmsh to 3D mesh the volume inside, am I right ? If that is the case, have a look at :

·         the tutorial example 13 (id & password = gmsh) : https://onelab.info/svn/gmsh/trunk/tutorial/t13.geo

·         this thread on the mailing list : http://onelab.info/pipermail/gmsh/2017/011096.html

Hope this helps,



Faithfully Yours,

Hi,



I have a problem converting a 2d mesh to 3d mesh.

I think the mesh is closed.

Does surface element orientation matter?



The error was



Info    : 0 points 0 edges and 0 faces in the initial mesh

Error   : No tetrahedra in region 30 0

Info    : 3D point insertion terminated (0 points created):

Info    :  - 0 Delaunay cavities modified for star shapeness

Info    :  - 0 points could not be inserted

Info    :  - 0 tetrahedra created in 0 sec. (-2147483648 tets/sec.)

Info    : Done meshing 3D (0.008999 s)

Info    : 267 vertices 0 elements

Error   : ------------------------------

Error   : Mesh generation error summary

Error   :     0 warnings

Error   :     1 error

Error   : Check the full log for details

Error   : ------------------------------



Thank you for your help



Best regards,
