WebA polyhedral mesh can be created by combining tetrahedral cells into polyhedral ones. Considering the tetrahedral mesh that has been generated for the 90° bend geometry in Fig. 4.5 , a polyhedral mesh such as shown in Fig. 4.6 can be created via cell agglomeration, which results in a considerable reduction of the overall cell count.
