Tetrahedral Volume Elements The polyhedral mesh is derived directly from the tetrahedral mesh by forming polygons around each node in the tetrahedral mesh. Volume Element Counts Convergence The pressure residual for each mesh type is shown below. Pressure Residuals Monitor The solution on the polyhedral...
hybrid tetrahedral-prism meshes for the same flow field. Solution convergence time with polyhedral elements was found to be 50%–140% higher than with hexahedral meshes of comparable size. While application dependent, the increase in simulation time observed with polyhedral meshes will likely be ...
