fluent6.3 以上版本也可以转换出多面体网格:
Support for polyhedral meshes is being introduced in FLUENT 6.3. These
meshes allow the flexibility of an unstructured mesh to be applied to a
complex geometry without the overhead associated with a large tetrahedral
mesh. Polyhedral meshes are created using automatic cell agglomeration
within FLUENT 6.3 to combine tetrahedral cells into polyhedral ones. This
can reduce the overall cell count by a factor of 3 to 5. Alternatively,
cell-skewness based agglomeration can be used to convert regions with
highly-skewed cells to polyhedra, thereby improving mesh quality. The
automatic nature of these mesh agglomeration techniques saves the user time,
and since the polyhedral mesh contains as few as 1/5 the number of cells in
the original tetrahedral mesh, convergence is faster. |
