Hi! I am trying to extrude a surface by rotating it, then process the 3D mesh in openflower. Extruding seems to create some errors - line 34 : Explicit region numbers in layers are deprecated I can then generate a 3d mesh, but there is one error - Cannot tetrahedralize volume with quadrangles on boundary Openflower crashes when trying to run the .flw file.
I have copied the following code, but don't understand where to get the
numbers from in the layers expression - Layers { 6, 54, 1 } could this
be the problem?
Extrude Surface {12, {0,0,1}, {0,0,0}, 2*Pi/3} {
Recombine ; Layers { 6, 54, 1 } ;
} ;
Extrude Surface {64, {0,0,1}, {0,0,0}, 2*Pi/3} {
Recombine ; Layers { 6, 311, 1 } ;
} ;
Extrude Surface {116, {0,0,1}, {0,0,0}, 2*Pi/3} {
Recombine ; Layers { 6, 568, 1 } ;
} ;
.geo .flw and GMSH error log attached.

Many thanks!!
