Descrizione

Our mission is to develop innovative solutions for the industry. Our main product RBF Morph is a ground-braking system for morphing and shape optimization tailored for ANSYS FLUENT.

RBF Morph is a unique morpher that combines a very accurate control of the geometrical parameters with an extremely fast mesh deformation, fully integrated in the ANSYS CFD solving process. RBF Morph is the meeting point between state-of-the-art scientific research and top-level industrial needs.

Most important industrial requirements, like process integration, mesh-independent solution, parallelism, large models and arbitrary mesh element type management, are fulfilled by RBF Morph. The final goal of RBF Morph is to perform parametric studies of component shapes and positions typical of the fluid-dynamic design like multi-configuration studies, sensitivity studies, design developments, DOE (Design of Experiment) and shape optimization.





RBF Morph Add-on for ANSYS Fluent

The add-on version of RBF Morph allows for shape optimization studies entirely within ANSYS Fluent by morphing an existing mesh. This new approach takes advantage of the ANSYS Fluent’s CFD technology and overcomes the limits of the mainstream methods, by introducing these functionalities through the implementation of dedicated routines in the CFD ANSYS Fluent code.

A dedicated Graphical User Interface (GUI) has been developed and integrated in ANSYS Fluent. The product is CFD users oriented and does not require the knowledge of other software packages.

The main features of the add-on are:

  • Product Integration: full integration with ANSYS Fluent.
  • User Interface: dedicated GUI and TUI (scriptable).
  • Process Integration: morphing directly inside the solving stage without modifying the geometry, regenerating the mesh and setup again the case.
  • Mesh Topology: modification of the original surface and volume mesh producing a nodal smoothing without changing the mesh topology.
  • Surface Morphing: surface mesh can be modified by free surface deformation, rigid movement or scaling.
  • Volume Smoothing: high quality smoothing of the volume mesh with relatively large movements possible in a single step deformation.
  • Versatility: nodal smoothing is achieved by means of a mesh-less approach that is independent from the mesh structure, handling every kind of mesh element type (tetrahedral, hexahedral, polyhedral, prismatic, hexcore, non-conformal interfaces, etc.).
  • Reusability: the RBF solution can be applied to any different mesh representing the same geometry.
  • Consistency: mesh characteristics are preserved so mesh consistency is ensured (element size, type and distribution, prism layers, etc.).
  • Parallelism: parallel calculation for large models (many millions of cells).
  • Efficiency: flow solutions are fully readable through all the morphed mesh, reducing the number of iterations to converge.
  • Precision: exact movement is ensured for the moving nodes locations as well as exact feature preservation.
  • Parameterization: multi-parameter and multi-step problems.
  • CAD: transfer modifications back to CAD by applying to STEP files similar modifications done on the mesh, in order to fully support the re-design of the morphed surfaces.



RBF Morph ACT Extension for ANSYS Mechanical

RBF Morph ACT Extension is powered by the high-performance numerical engine of RBF Morph technology and comes with full support of ANSYS Mechanical.

The new product of RBF Morph has been developed through the ACT customization platform of ANSYS and, since it is fully embedded in ANSYS Workbench, it allows to drive your optimizations using the same DesignXplorer parameters and scoping tools that made ANSYS your favourite FEA analysis tool.

Main features of the ACT Extension are:

  • fully embedded in ANSYS Mechanical GUI, same "look&feel" and interaction logic
  • fast RBF library with CUDA and OpenMP acceleration
  • hierarchical set-up to guarantee the maximum flexibility
  • parameters can be added as usual checking with a "P" the desired field
  • optimal geometry can be transferred back to CAD
  • plenty of basic shape modifications (Translation, Rotation, Scaling, Surface Offset, Curve Offset, Surface Target, Curve Target)
  • complex shape modifications can be created using hierarchical approach to create non linear chains of multiple modifications
