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.

In a recent publication in the renowned journal Optica, scientists of Leibniz-Institute of Photonic Technology (Leibniz IPHT) in Jena showed that they can accurately control the optical properties of liquid-core fiber lasers and therefore their spectral band width by temperature and pressure tuning.
Already last year, the researchers provided experimental proof of a new dynamic of hybrid solitons– temporally and spectrally stationary light waves resulting...

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.
Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...
The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.
Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.
An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.
Endoscopes allow doctors to see into a patient’s body like through a keyhole. Typically, the images are transmitted via a bundle of several hundreds of optical...
