Many of the most challenging aspects of propulsion system development are related to the prediction of interacting effects among fluid loads, thermal loads, and structural deflection. A typical design practice might ignore the interaction between the physical phenomena where the outcome of each analysis can be heavily dependent on the inputs. Such a rigid design process also lacks the flexibility to employ multiple levels of fidelity in the analysis of each of the components.

The use of commercially available software products to design and analyze complex turbomachinery has become more commonplace. At the same time, companies want access to legacy codes that often are well validated against historical test data. This software is an integrated framework for turbomachinery analysis, and reduces the time and complexity of the multiphysics analyses. The software allows these codes, provided from diverse commercial and internal sources, to complement each other.

The project developed innovative design and analysis tools that have the flexibility to analyze simultaneously multiple disciplines and multiple components, with multiple levels of model fidelity.
