CPTCDX – Not your father’s DX!
Overview
Cornell Fracture Group research scientists perform computational fracture mechanics simulations to better understand and predict the failure of structures due to cracking. The spatial and temporal scales of the physical phenomena simulated span nanometers to meters and nanoseconds to years. Traditional engineering tools are not sufficient to deal with the multi-scale nature of these simulations.
At the Cornell Theory Center, we are synthesizing a new environment for multi-scale, multi-physics simulations.
- Simulation input is read from a Microsoft SQL Server 2000 database running on different multiprocessor configurations.
- The simulations are run in parallel on a Microsoft Windows 2000 cluster of Dell PowerEdge servers using Intel Xeon and Itanium processors.
- Simulation output is stored in SQL Server databases and subsequently accessed by various post-processors.
We have developed an innovative real-time visualization tool for interactive exploration of large-scale 3D solid models and underlying engineering data. Users guide dynamic data extraction by manipulating visual probes and selectors (Figure 2, Figure 3, Figure 5). These choices are automatically translated by the system into SQL queries, which return new features to the user’s display. Advanced users who need greater flexibility can directly type their own SQL queries via a simple form (Figure 4).

Novelty
From commodity soft- and hardware components, we put together a scalable solution for real-time interactive visualization and computational steering on the Windows platform.
