Dear All, Thanks for the great work on FiPy so far.
We have a 2nd order elliptic PDE* defined in the domain (0, 1). At each boundary, we have a no-flux boundary condition. We have tried to represent this in FiPy, but specifying such conditions results only in incorrect results with large error. We have searched this page (below) in depth but can't see which function call is appropriate, if any. http://www.ctcms.nist.gov/fipy/fipy/generated/fipy.boundaryConditions.html Do you have a recommendation for how we may implement two no-flux boundary conditions on our PDE? Best regards, - Ian * $$\nabla.(\sigma_{eff} \nabla \bar{\phi}_s) = a_s F \bar{j}$$ Ian Campbell | PhD Candidate Electrochemical Science & Engineering Group Room 506, City & Guilds Building, Imperial College London, SW7 2AZ, United Kingdom Phone: +44 (0)7449 815 520 | E-mail: [email protected]
