Coming up soon: With the next major release, FRIENDSHIP SYSTEMS will provide the first version of its freeform deformation, greatly complementing the existing shift transformations of CAESES. This new functionality allows users of CAESES to easily deform imported CAD geometries and CAE data such as volume meshes. Naturally, the design variables of such a user-defined transformation can be controlled by the variation and optimization engines of CAESES, for conducting fully-automated shape studies.
Deformations can additionally be used in conjunction with adjoint sensitivities, in order to find the most important deformation variables. Check out this case study which is related to mapping geometry parameters to adjoint sensitivities.
