WP 3- Simulation tool

The Inachus Workpackage 3 part will provide 3D- simulations of disaster areas on two scales. On the urban scale a simulation tool for urban planning (VITRUV) will be adapted to provide digital maps with immediate assessment of overall building damage. This will help USaR (urban search and rescue) teams to find hot spots of highest damage and potentially trapped victims and rescue paths to them before entering a disaster area.

On the building scale software will enable building collapse simulations of different building types and different building methods, concrete, steal etc. A rescue site USaR teams will have access to a building library with pre-defined typologies that can be subjected to a number of collapse scenarios. The behavior of tumbling building structures can so be studied and the USaR teams will be adverted to the general risks during and after a collapse.  Methods will be studied  how rubble heaps and partially collapsed buildings can be scanned for cavities where survivors could be trapped so that rescue paths in the building can be planned.

Three computational simulations methods will be examined: The finite element method FEM (by EMI, Fraunhofer-Gesellschaft), the applied element method (by ASI, applied science international) and the discrete element method (by LAUREA, university of applied sciences)

What is the Laureas part in Inachus´ work package 3 ?

The aim of this development is to complement the bullet physics engine in the open source program Blender with a tool set (add-on) that allows to attribute realistic structural dependencies to building elements such as pillars, walls, beams, slabs etc. The tool set in conjunction with the bullet physics engine should deliver satisfactory simulation results. The way the bullet physics library is computing simulations is commonly referred to as Discrete Element Method or DEM.
