Case Study: General Electric achieves automated, high-quality all-hex combustor meshing with ANSYS CFD

General Electric - Customer Case Study

General Electric faced a complex, multidisciplinary aircraft‑engine combustor design challenge requiring aero CFD, combustion and heat‑transfer analysis as well as dynamics and life prediction. To meet aggressive new‑product‑introduction (NPI) analysis requirements they needed automated, scriptable mesh generation that produced high‑quality all‑hex meshes; they chose ANSYS and used ANSYS CFD (hexa) for its scripting capabilities and strong Unigraphics interface.

ANSYS implemented automated meshing strategies for the full combustor sector—partitioning the model into innerliner, outerliner and dome assemblies, generating tetin files (prt2tetin), creating hexa replay files and integrating component meshes—to deliver an all‑hex mesh workflow. The ANSYS solution enabled multidisciplinary design optimization, streamlined UG geometry translation, reduced manual meshing intervention, and provided robust mesh export options and prompt technical support to help General Electric meet its aggressive analysis timelines.
