Problems of this type can be found in several application domains, e.g. in simulations of oil reservoirs, automotive design and also simulations relevant for environmental analyses, such as groundwater flow. SAMG is developed by the Fraunhofer Institute for Algorithms and Scientific Computing (SCAI).
The software package SAMG was developed for highly efficient, numerical solutions of large, sparsely populated matrix problems. Problems of this type can be found in several application domains, e.g. in simulations of oil reservoirs, automotive design and also simulations relevant for environmental analyses, such as groundwater flow. SAMG is developed by the Fraunhofer Institute for Algorithms and Scientific Computing (SCAI).
The MODFLOW software from the U.S. Geological Survey (USGS) organization simulates flows in groundwater reservoirs, to show transport and diffusion of certain materials (e.g. pollutants). The combination of SAMG and MODFLOW accelerates groundwater simulations enormously. The gain in computation time in solving large systems can be of orders of magnitude. This makes the software the first choice for companies and those seeking to optimize use of computing resources.
The SAMG-MODFLOW package now available online includes the SAMG Library (dll) customized for MODFLOW, MODFLOW 2005 linked to the SAMG Library, documentation, test models as well as an interface description to allow users to link SAMG to their MODFLOW variant.
A 30-day evaluation license for SAMG for MODFLOW is available at no cost and until June 30, 2012, there is a 30% discount on both the research and regular licenses. MODFLOW itself remains of course free of charge. Please visit the online shop of SCAI´s sales spin-off scapos AG under www.scapos.com

MPQ scientists achieve long storage times for photonic quantum bits which break the lower bound for direct teleportation in a global quantum network.
Concerning the development of quantum memories for the realization of global quantum networks, scientists of the Quantum Dynamics Division led by Professor...

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
