Hi Burak,
The getGrad operator doesn't include the boundary condition in its
evaluation. Reading <

Dear all,
I was wondering if there is an error in getGrad() within FiPy. For testing I
solved a really simple 1D differential equation ending up with a linear slope.
The value which I get from getGrad() are ok for all cells, except the ones at
the boundaries, where they are off by a factor of 2. (S
