Hi, I am a novice user of FiPy and am interested in modeling reaction-diffusion phenomena in an axisymmetric cylindrical geometry.
The cylinder comprises two concentric regions (a 'core' and 'annulus') that have different properties. What is the preferred method to deal with the two regions (and potentially different governing equations in the regions)? Is this possible with a single mesh? If not, could I create two 'CylindricalGrid2D' meshes, with the annular region utilizing the 'offset' argument from the core region? If two meshes are used, how does one assure continuity between quantities at the interface between the regions? Thank you very much for any advice or recommendations. Best Regards, Brad
