Fraunhofer SCAI’s leading software SAMG accelerates groundwater simulations

29.05.2013
Fraunhofer SCAI’s linear solver library SAMG (Algebraic Multigrid Methods for Systems) for the acceleration of groundwater simulation software.

Leading global companies like Schlumberger Water Services, Aquaveo LLC, DHI Water & Environment, Environmental Simulations Inc., and HydroGeoLogic Inc. exploit Fraunhofer SCAI’s linear solver library SAMG (Algebraic Multigrid Methods for Systems) for the acceleration of their groundwater simulation software.

Groundwater models are the basis for computer simulations for a range of industrial and environmental research themes, such as analyses of pump testing, the diffusion of toxic elements, and the prediction of changes in groundwater levels. The computationally most intensive process during a groundwater simulation is the solution of the extremely large linear systems of equations.

By using the industry-leading library SAMG, computing times can be reduced enormously. SCAI’s software allows the user to increase modeling accuracy and at the same time keep compute times manageable. Furthermore, SAMG handles strongly heterogeneous systems like hydraulic conductivity systems where standard solvers fail. SAMG is available for use with the MODFLOW-software from the United States Geological Survey (USGS) and visitors to the MODFLOW & More conference to be held in Golden, Colorado in the first week of June will have a chance to find out more about the software.

SAMG is a library of subroutines for the highly efficient solution of large, sparse linear systems of equations. Such systems of equations form the numerical kernel of most simulation software packages. Usually, the numerical solution of these linear systems of equations needs most of the computational time of the whole simulation. SAMG supports both serial and multi-core computations on single PC, workstation or compute nodes.
The work of Fraunhofer SCAI is dedicated to partners and customers involved in software development and applications. In addition to the solver technology, SCAI offers analysis and advice on application problems as well as tailoring of the software to the customers’ computer systems, in particular for parallel computers.

Im Focus: Dresdner scientists print tomorrow’s world

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.

The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Im Focus: Three Magnetic States for Each Hole

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".

Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
