WestGrid Seminar Today - March 5

Interoperable Mesh Tools for PDE Simulations

Carl Ollivier-Gooch, University of British Columbia

12:00 PST / 13:00 MST / 14:00 CST

All PDE-based numerical simulation software must be able to access and manipulate mesh data, and an increasing number of simulations require the ability to adapt the mesh based on solution data. However, such sophisticated mesh manipulation operations are quite difficult to implement well. The obvious solution to this --- mesh adaptation libraries --- does not work well in practice because these libraries require specific data structures.

This talk will describe a mesh component architecture that overcomes this problem. The mesh component has a defined data model --- describing what data must be represented, but not how --- and a defined interface for accessing and manipulating that data. Applications and services such as adaptation interact with mesh data through the interface. A key advantage of the component architecture is that services can be used with any mesh database that supports the interface, including data native to a particular application with the interface functionality added on top of it.
The talk will include a description of the mesh component data model and interface, as well as several usage examples, from simple to relatively sophisticated.
