electrorefiningFoam

It is described how to simulate current distributions in electrochemical reactors under natural convection flows using OpenFOAM. The process of pre-processing, running, and post-processing a basic 2D case using the developed solver electroNaturalConvectionPimpleFoam and codedMixed boundary condition (BC) is demonstrated. The proposed strategy is fully functional in OpenFOAM version 7 and OpenFOAM 2312.
