Craig's ML-DDDAS Group

Introduction

The multilevel, dynamic data-driven application simulation (ML-DDDAS) group is an outgrowth of Craig Douglas' research in multigrid methods, hardware assisted (i.e., cache aware) multigrid methods, and DDDAS. Our research has been generously supported over more than 25 years by the National Science Foundation, Sandia National Laboratories, the North Atlantic Treaty Organization, teh University of Wyoming, the University of Kentucky, Yale University, Duke University, CERFACS (France), the Johannes Kepler Universitšt Linz (Austria), LNCC (Brasil), Hewlett-Packard, Intel, and International Business Machines.

We strive to bring fast, accurate algorithms to computational scientists using the latest algorithmic and data-driven techniques. Application fields that we have addressed or are addressing include

  • Energy resource modeling
  • Wildland fire simulation
  • Contaminant transport simulation
  • Ocean modeling
  • Flame simulation

Current Group Members

The group is far flung across the globe with strong ties to our group through cooperative research arrangements.
