specializations of *vtkConvexPointSet *
I wonder whether this may be the root of the problem outlined in

Dear All,
This question is loosely related to
https://github.com/usnistgov/fipy/issues/312 but might perhaps not be
exactly the same. I ran some tests in which I tried to plot a "broken" mesh
by resetting the cell type of the underlying tvtk object the same way
fipy's VTKCellDataSet method does:
TK_CONVEX_POINT_SET. I have a (stalled) development that does a better job

Is the choice of the cell type intentional or important here? If so it
might be worth convincing those libraries to add cell type 41 plotting and
i/o capabilities.

Dear All,
I'm just getting back into using fipy after a few months hiatus. I'm
getting more familiar with how it works, but I have a couple of questions
about the viewer:
- Is it possible to control linestyle (specifically dashes) of the
cellVariable objects tied to each specific viewer? I
Dear all,
I have a question not too unrelated to this one. Let's say I have a 2D
numpy array and I want to assign its value to a cell variable defined
over a 2D mesh of the same dimensions. Is there any simple way to do
that.
n = 5
mesh = Grid2D(nx = n, ny = n)
k = rand(n,n)
phi = CellVariable(me
Hi Daniel,
In your script, you are solving an steady state problem. Add a transient
term, and preferably sweep to get the solution. Perhaps sth like this:
equation = (TransientTerm() == diffusion_term + source_term)
timestep =
steps = 10
for step in range(steps)
res = 1.e6

Hello all,
I'm using fipy to solve flow in porous media problems, and I must say
with the new version (3.0) there is no problem in solving single phase
multi-component convection diffusion equation coupled with Darcy's law.
My difficulty is with solving two-phase flow and specially
