Solution of Box, AvgMPFA, NLTPFA, and NLMPFA schemes (first row); solution of MPFA-O, TPFA, MFD, and HFV schemes (second row) for the first discrete extremum principle test case calculated on the grid that arises after three times refinement of the grid shown in Figure 5. The tensor is specified in (53). The range of the different solutions is depicted below the different drawings.
