The moment-of-fluid interface reconstruction method has shown dramatic improvements in advection tests, but this did not create an equivalent improvement in the volume-tracked flow simulations using low-order elements. The effects of the spatial discretization, using Q1Q0 or Q2P−1 elements, combined with first-order and second-order interface reconstruction methods are examined. The Q2P−1 elements show reduced convergence in volume-tracked simulations. Although momentof-fluid shows some benefit of higher-order elements, the accuracy improvements shown in the advection tests are not recovered.
