G3DHexa is a structured 3D multiblock mesher for the generation of high quality grids for CFD applica-tions in turbomachines.The software package G3DHexa has been used in DLR since 2001 and has been successively improved and extended in terms of various geometry application
aspects.As a pre-processing tool the grid generator is strongly coupled with the DLR flow solver TRACE. G3DHexa is also used for mesh generation at a large number of national universities.In the German turbomachine industry G3DHexa has, since 2001, been integrated in the design process for compressors and turbines at MTU Aero Engines in Munich.The most important features of the grid generator are as follows :
POST is a block-parallelized post-processing-tool developed especially to analyze multi-stage turbomachinery components. The applications range from the calculation of 3D field variables over averaged 2D- and 1D-distrubitions to global indicators and ratios of the turbomachine. The core
item and main application of POST is the general analyses of turbomachines. It is composed of circumferential averaged radial distributions, blade distributions as well as global performance values like the efficiency factor for the whole component. POST is able to process both steady and unsteady data sets.
Because POST is used for research purposes as well for the industrial design process, it is designed in a modular manner and can be easily adapted or extended by the users to fit their requirements.
