- In this paper, we extend the idea of MLP to three-dimensional space and
present the multi-dimensional limiting process for three-dimensional flow. The
basic idea of the multi-dimensional limiting condition is that the vertex values
interpolated at a grid point should be within the maximum and minimum
cell-average values of neighboring cells for the monotonic distribution. By
applying the MLP (Multi-dimensional Limiting Process), we can obtain nonoscillatory
shock profile even in multiple dimension, which results in very good
convergence characteristic. Furthermore, while maintaining the oscillation-free
attribute, we can achieve an enhancement of solution accuracy by combining
the MLP with high-order polynomial interpolation.
