Aside from stress results, the structural analysis delivers structural displacement results, which can be used to address an additional complexity in turbomachinery: the so-called cold-to-hot deformation. Components such as fan blades of a gas turbine undergo deformations due to high rotational speeds and fluid pressure forces. Therefore, the at-rest “cold” shape used for manufacturing differs from the operational “hot” shape. These deformations can have a significant impact on the engine's efficiency. The inclusion of a differentiated cold-to-hot CAD deformation allows us to directly include deformation effects within the optimization process, rather than as a post-processing step after the optimization.
