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

The well-known representation of chemical elements is just one example of how objects can be arranged and classified
The periodic table of elements that most chemistry books depict is only one special case. This tabular overview of the chemical elements, which goes back to...
Light can be used not only to measure materials’ properties, but also to change them. Especially interesting are those cases in which the function of a material can be modified, such as its ability to conduct electricity or to store information in its magnetic state. A team led by Andrea Cavalleri from the Max Planck Institute for the Structure and Dynamics of Matter in Hamburg used terahertz frequency light pulses to transform a non-ferroelectric material into a ferroelectric one.
Ferroelectricity is a state in which the constituent lattice “looks” in one specific direction, forming a macroscopic electrical polarisation. The ability to...
Researchers at TU Graz calculate the most accurate gravity field determination of the Earth using 1.16 billion satellite measurements. This yields valuable knowledge for climate research.
The Earth’s gravity fluctuates from place to place. Geodesists use this phenomenon to observe geodynamic and climatological processes. Using...
Discovery by Brazilian and US researchers could change the classification of two species, which appear more akin to jellyfish than was thought.
The tube anemone Isarachnanthus nocturnus is only 15 cm long but has the largest mitochondrial genome of any animal sequenced to date, with 80,923 base pairs....
Researchers at Chalmers University of Technology, Sweden, have discovered a completely new way of capturing, amplifying and linking light to matter at the nanolevel. Using a tiny box, built from stacked atomically thin material, they have succeeded in creating a type of feedback loop in which light and matter become one. The discovery, which was recently published in Nature Nanotechnology, opens up new possibilities in the world of nanophotonics.
Photonics is concerned with various means of using light. Fibre-optic communication is an example of photonics, as is the technology behind photodetectors and...
