FINE™/Design3D

The unique optimization software for your CAE environment

Optimizing your design starts here.

FINE™/Design3D is a unique optimization framework allowing for multidisciplinary, multiobjective design optimization - all based on the highly efficient DoE generation and surrogate modeling of Minamo.

With the added option of uncertainty quantification, engineers can design under real-world conditions, taking into account variations on input conditions, geometry or a combination, and ensuring performance within the design envelope.

Connected to all NUMECA software solvers, and open to other software codes, FINE™/Design3D can be customized for easy integration into the design process. 

See the full workflow in action in this video.


Parametrization

Smart parameterization is key to the success of optimization. 

AxCent™ and Autoblade™ provide parameterization environments dedicated to turbomachinery.  They offer flexible modeling to define a large design space and can easily handle all types of turbomachinery blading systems, with classical design models based on blade sections, camber, thickness, and stacking.

For marine design projects, NUMECA has developed a direct plug-in with the Grasshopper geometry modeler, enabling naval architects and marine engineers to easily create 3D geometries.


Morphing and adjoint solvers

A powerful alternative to a dedicated parameterization tool, morphing method allows engineers to modify, or deform, a non-parameterized geometry or mesh. 

Arbitrary changes in the body shape can be achieved without changing the mesh topology: control points become the parameters of the optimization.

All the features for efficient exploration of the design space can be achieved with Minamo's DoE and optimization algorithms, or by coupling to an adjoint solver.


Optimizing the Design of Experiment

 

The optimization kernel Minamo is developed by Cenaero and based on the Design of Experiment (DoE) technique

The way the design space is explored has a huge impact on the convergence of the optimization and on the search for the optimum value.

Minamo includes superior space-filling techniques that greatly reduce the number of samples needed for a design of experiments.

Auto-adaptive DoE techniques are also available for efficient handling of high-dimensional design spaces, as well as highly constrained optimization problems. 

A task manager enables spreading the CFD runs on a cluster, for the generation of multiple samples in parallel.


Optimization and surrogate modeling with Minamo

The surrogate model rapidly speeds up exploration of the design space by approximating the solution in between the DoE points of the sampled design space.

Several algorithms are available, from Artificial Neural Networks to Radial Basis Function Networks (RBF) and Kriging. The surrogate model is then used to apply an iterative optimization algorithm and find the global optimum.

This approach produces benefits at different stages of the development process, from the early concept definition to the final design phase, and speeds up the development cycle of complex products by reducing computational costs related to high-fidelity simulations.


Data-mining & analysis

Analysis of Variance (ANOVA) 

Data-mining algorithms are used to get a deeper understanding of the design space and to provide more insights during the optimization process, thus reducing the CPU cost of the overall optimization

Based on the surrogate model, Analysis of Variance  (ANOVA) provides information on which design variables have more influence over the outcome.  

Self Organizing Maps project high-dimensional data onto a low-dimensional (typically 2D) map. These visual inspection tools are useful for revealing major trends and discovering correlations and anti-correlations among parameters and/or responses.

 


Multidisciplinary design optimization

An optimization process is stronger if it can account for off-design conditions, mechanical reliability, noise, and other aspects such as manufacturing costs. FINE™/Design3D has been developed in order to allow for that flexibility, with the possibility to call a flexible amount of evaluators and solvers.

All the solvers, CFD, acoustics, and structural can be coupled and included within the analysis phase, with a flexible open framework, where users can plug in all NUMECA and external solvers to benefit from state-of-the-art technology.

Additionally users can optimize not only the design performance, but ensure and control operating range by including multiple operating conditions in the analysis.


Uncertainty Quantification and Robust Design Optimization

CFD and design procedures have always been applied assuming geometries and operational conditions are well known. In reality they are subject to manufacturing variability and variable operating conditions.

Uncertainty quantification allows to acount for these uncertainties and estimates their impact on system performance. It can be used to identify variables with the largest sensitivity for instance, or calculate the impact of less stringent manufacturing tolerances.

In design mode, uncertainty quantification enables minimizing the impact of uncertainties on performance, ensuring that the final design performance is robust. The performance will be less sensitive to the variability of those uncertain variables.
