CRESENDO Project

Project Summary

In collaboration with major European Aircraft and Engine Manufacturers, research Organizations and Universities.

This project covers a lot of research areas with the CEIAT staff mainly working on the research of efficient meshing and cellular modelling.

Efficient meshing requires specialised software programs.  The development of better algorithms has allowed the available mesh elements and mesh connectivity to expand.  A structured mesh has regular connectivity allowing space to be conserved.  An unstructured mesh has irregular connectivity and hybrid meshing contains both structured and unstructured portions.  Meshes can also be classified based on the dimension of the elements present.  However all 3D elements are bounded by 2D elements.

The meshing works by sub-dividing a complicated domain into a series of smaller regions in which differential equations can be used to approximated solutions.  This allows the domain behaviour to be determined.  Each region is called an element and elements are connected at specific points called nodes.

Cellular modelling involves the development of the efficient algorithms or meshing.  With the use of computer simulations the cellular models can be analysed and the complex connections can be visualized.  A structure is broken up into sub-structures called cells and the essential intra cellular details are retained as parameters.
