Numerical Analysis Sub-System

Requirements definition

The main purpose of Computational Fluid Dynamic (CFD) analysis of the biomedical devices prototypes, selected as study cases, is to provide complementary information to PIV results, thus locally contributing to their validation. These numerical simulations will fruitfully support the experimental tests through the characterisation of the local fluid dynamics, especially in those areas of the biomedical device prototypes which are not accessible to PIV measurements. In the view to pursue this goal, an initial effort was devoted to the definition of technical requirements, with particular reference to the following aspects:

definition of pre-processing module demands, in terms of meshing capabilities, flow model solutions especially suitable to solve unsteady and turbulence problems and related elements libraries;

definition of required parallel processing capabilities in relation to the CPU time needed to perform a complete analysis of the selected study cases and to the possibility of interfacing the parallel computing network;

definition of required user defined subroutines necessary to simulate the physical phenomena involved in the two study cases in the most realistic way allowed by the current state-of-the-art numerical technology.
