Shape Deformation

Shape Deformation and Morphing

Shape deformation and morphing techniques help you to quickly optimize existing geometry. With this additional capabilities, CAESES® focuses on CFD engineers that want to import and reshape their design with regards to the flow performance.

Import geometry, create a deformation and reshape your design. Fast and easy.

Applying deformations can be done manually or fully-automated. Based on imported geometry e.g. from STL data, you can apply box deformations and other methods such as Radial Basis Functions (RBF). Boxes can be created along a path, for example. The user can even define own custom boxes and transformations by using so-called feature definitions.

 

Free Form Deformation

Here is a short video to get a first idea of free form deformations, and see this blog post about re-shaping a fuel injector design with free form deformations.

RBF Morphing

CAESES® provides RBF functionality for fast deformations of existing geometries. Please get in touch with us if you are interested in it.

 

 

Transfer to the Downstream CAD System

Deformations can be applied to NURBS surfaces and to discretized data. For instance, when deforming the surface triangulation of a geometry, you can afterwards also apply the same deformation to the surface geometry (if available) from which the triangulation was derived. This means you do not have to re-model the changes in your downstream CAD system, instead you can hand over the modified CAD geometry by e.g. using the STEP export of CAESES® for the deformed surface geometry.
