At the Italian Conference AIAS 2015 on 2-5 of September in Messina we present two projects; the first project is an industrial application of SACMI based on RBF Morph and Ansys Mechanical: starting from a defined topology the paper shows how mesh morphing can be used to obtain the best shape in terms of component reliability.
In the second project a procedure to optimise the shape of a connecting rod subject to inertia loads is showed.

It is well known that shape optimization is a way to improve the structural performance of components and tools based on parametric geometries are becoming standard for fine-tuning optimization processes in industry.
These tools can handle different types of structural analysis, but they are limited by difficulties in maintaining geometry coherence.
Direct update of nodal positions of finite element models by mesh morphing is a meaningful alternative to re-meshing a parametric geometry, helping the designer in what-if studies, optimization and robust design development without geometry coherence problems.
Radial Basis Functions (RBF) are recognized among the best mathematical tools to perform mesh morphing.
An industrial implementation of RBF is available in the software RBF MorphTM born for CFD applications and now available in ANSYS Mechanical as an Extension created using the new Application Customization Toolkit (ACT) of Ansys®.

Structural optimisation allows to minimize the inertia of a mechanical component with an acceptable effect on its strength.
In this paper a procedure to optimise the shape of a connecting rod subject to inertia loads is showed: the analysis is performed by the DOE method and it aims to set the dimensions of two lightening holes drilled on the connecting rod body.
The damage mechanism considered is fatigue.
This method, implemented in ANSYS® Workbench, is highly automated, after eachshape change inertia loads are updated and results are showed as damage contours. The entity of optimisation is evaluated in terms of mass and moment of inertia reduction.
