bitpit: a numerical sandpit for bridging scientific computing and 
industrial applications.

Traditionally scientific computing is being delivered to industry by 
means of packaged software with pre-defined functionalities, developed, 
maintained and delivered by independent software vendors. Within this 
approach, vendors will pick promising research results obtained by 
accademia which fit their development plans and integrated them into 
their software.

Contemporarily, a lot of research results in the field of mathematical 
modelling and numerical methods remain unexplored, since accademia may 
not address autonomously all the efforts which are necessary in order to 
transform a numerical proof-of-concept even into a prototype to be 
tested in an industrial framework.

bitpit is a communicating collection of open-source C++ libraries and 
interfaces to third party libraries, which aims at helping the 
scientific computing community to deliver easily a first prototype of 
their application to industry.
The general design philosophy is to transfer complexity from humans to 
the machines by relying massively on HPC resources: easy but scalable 
algorithms are preferred over highly-optimised variants even if they may 
perform better on workstation-like computers.

The different layers of bit pit read:
Interfaces (PETSc, LAPACK, DAKOTA,)
FileIO (CAD and image formats and visualisation)
Computational Geometry ( explicit and implicit representation of 
surfaces, boolean operators, parameterisation and deformation, discrete 
mappings )
Discretization ( Adaptive Octree grids, Unstructured grids, Cartesian 
grids and polymorphic interface )
Solvers ( Immersed Boundaries Compressible Fluid solver,  Crowd dynamics,  )
ROM ( POD-based,  Domain decomposition)

Within this talk the general architecture of the bitpit framework and 
the state of its implementations will be illustrated. Furthermore 
applications from the automotive and aeronautical industry as well as 
from urban planning will be presented.
