Mesh convergence criterion. Relative difference in electrodic dimensionless current compared with the most accurate d = 0.01 du taken as reference. Five channel heights were considered, namely A = 1, 2, 3, 4, and 5 du. The mesh size d = 0.02 du significantly reduced the discrepancy in current values with the reference mesh size d = 0.01 du, if compared with the less accurate mesh size d = 0.1 du.
