Right. I remember. You can extrude from any 2D mesh. I fixed all that
when you were here.
This is from help(Grid2D().extrude)
Help on method extrude in module fipy.meshes.numMesh.mesh2D:
extrude(self, extrudeFunc=<function <lambda>>, layers=1) method of
fipy.meshes.numMesh.uniformGrid2D.UniformGrid2D instance
This function returns a new 3D mesh. The 2D mesh is extruded
using the extrudeFunc and the number of layers.
:Parameters:
- `extrudeFunc`: function that takes the vertex coordinates and
returns the displaced values
- `layers`: the number of layers in the extruded mesh (number of
times extrudeFunc will be called)
>>> from fipy.meshes.grid2D import Grid2D
>>> print Grid2D(nx=2,ny=2).extrude(layers=2).getCellCenters()
[[ 0.5 1.5 0.5 1.5 0.5 1.5 0.5 1.5]
[ 0.5 0.5 1.5 1.5 0.5 0.5 1.5 1.5]
[ 0.5 0.5 0.5 0.5 1.5 1.5 1.5 1.5]]
>>> from fipy.meshes.tri2D import Tri2D
>>> print Tri2D().extrude(layers=2).getCellCenters()
[[ 0.83333333 0.5 0.16666667 0.5 0.83333333 0.5
0.16666667 0.5 ]
[ 0.5 0.83333333 0.5 0.16666667 0.5 0.83333333
0.5 0.16666667]
[ 0.5 0.5 0.5 0.5 1.5

1.5 ]]
