Visualization on Cover of Workshop Report
- July 2008
A visualization of pore-scale flow created by PNNL's John Serkowski was used as the cover illustration for the report from the workshop "Scientific Impacts and Opportunities for Computing". Tim Scheibe served as a panelist at the workshop and contributed to the report.

Computational Hybrid Integration of Physical Processes across Scales (CHIPPS) |
Hybrid Numerical Methods for Multiscale Simulations of Subsurface Biogeochemical Processes: In this SciDAC Science Application, we are developing an integrated multiscale modeling framework with the capability of directly linking different process models at continuum, pore, and sub-pore scales. These codes will be modified and/or developed using advanced high-performance component architectures and efficient parallel solvers, and will be integrated into a component-based workflow environment to facilitate seamless integration of codes operating at multiple scales with different physical, biological, and chemical conceptualizations appropriate to the needs of specific simulation problems.
