FINE™ / Design3D

Unique environment for the design and optimization of 3D turbomachinery configurations.


FINE™/Design3D is an integrated environment for the design and optimization of turbomachinery channels and blades. An optimization system requires a parametric modeler to define a large design space, an automatic and fast grid generator, an accurate and robust CFD solver, and an efficient optimization kernel. FINE™/Design3D meets all these requirements and enables designers to reach innovative turbomachinery geometries in an all-in-one structure:

– AutoBlade™: a 3D parametric blade modeler with an advanced fitting module to start designs either from scratch or from an existing geometry.

– FINE™/Turbo: NUMECA environment dedicated to turbomachinery flow analysis from mesh generation with AutoGrid5 to post-processing with CFView. It includes the 3D Navier-Stokes multi-block structured flow solver, recognized as the fastest and most accurate for turbomachinery configurations. Users can then benefit from the flow solver efficiency on both workstations or large HPC configurations.

– Design3D Optimization Kernel: an artificial intelligence combining the power of design of experiments, artificial neural network and advanced optimization algorithms.

FINE™/Design3D can be applied to a wide range of configurations: compressors, turbines, pumps, fan, propellers and contra-rotating propellers. Engineers will benefit from FINE™/Design3D to accelerate their design cycle and generate high performance turbomachinery geometries, taking into account their objectives and constraints. The net result is clear: the time-consuming trial and error process is replaced by an efficient self-learning algorithm.
