Finite Element Modelling

 


 

We use finite element analysis in the design process once the physics of a proposed concept has been understood, to converge to a design based on comparative iterations. There is a large number of examples where finite element modelling has been used to perform mechanical static and dynamic, thermal, fluid flow and other types of analysis, and a combination of them to understand multiphysics interactions. Two examples of projects are mentioned, where finite element modelling have been used for product development.

A microscopy stage using piezoelectric actuators for nanopositioning of microwell plates have been designed by using Ansys to understand the mechanical static and dynamic behaviour of the design. The result is a product on the market covered by a patent.

A printhead using piezoelectric actuators for droplet deposition was designed by using combining computational fluid dynamics, thermal and mechanical structural simulation to understand the interactions between these effects and their impact to the performance of the piezoelectric actuators. This work was concluded with a product on the market also covered by a patent.
