It is described how to simulate secondary current distribution (https://www.comsol.com/blogs/current...interface-use/) in electrochemical reactors with a multiregion approach (solve solid and fluid phases) with the help of OpenFOAM, the solver multiregionPotentialFoam and the BC regionCoupledSolidFluid. It shows how to pre-process, run and post-process (wallCurrentFlux) a basic case involving in a 2D domain.
