Hi FiPy Users,
I think Matplotlib 1.4.0-2 breaks FiPy's 2D viewers.
These are the versions supplied by Enthought Canopy's installation.
I can provide more detail, but I'm curious to know if anyone else has
experienced this.
The following code throws an error with Matplotlib 1.4.0-2 installed and works
with 1.3.1-9:
from fipy import *
L = 1.
nx = 400
dx = L/nx
dy = L/nx
mesh = Grid2D(dx=dx, dy=dx, nx=nx, ny=nx)
phase = CellVariable(name="phase", mesh=mesh)
x = mesh.cellCenters()[0]
y = mesh.cellCenters()[1]
phase.setValue(1.)
x0 = 0.0
y0 = 0.0
phase.setValue(0., where=(
((x-x0)**2+(y-y0)**2 > L/3) & ((x-L)**2+(y-L)**2 >
0.2)
)
)
viewer = Matplotlib2DGridViewer(vars=phase)
viewer.plot()
