Marquette University

Enhancing Data Analysis of Hemodynamic Flow Simulations with COVISE: Marquette University in Milwaukee, Wisconsin, USA

Researchers at Marquette University’s CVTEC Lab are working to develop efficient techniques for modeling and analyzing patient-specific models of coronary, carotid and cerebral blood vessels.  By obtaining Magnetic Resonance Imaging (MRI) data, researchers can construct computerized models of a patient’s blood vessel and perform computer analysis in order to quantify risk factors for aneurysm, stroke, atherosclerosis and other relevant pathologies.  By incorporating COVISE into the workflow, researchers gain a deeper understanding of the complex interactions between the vessel geometry, hemodynamic quantities such as velocity and wall sheer stress, as well as disease. 

Current projects include: modeling vasculature of children with congenital heart diseases, assessing hemodynamics in coronary vessels pre- and post-stent implantation, designing a mobile VR system optimized for a medical clinic, researching teaching and instruction methods for engineering and technology students by using VR, and cardiovascular stent design optimization using cost functions based on hemodynamic flow analyses.

Molecular dynamics simulations gain increasing impact in materials science and materials design. For this present study of ultra-hard metal-carbide layer systems, nanoindentation experiments were simulated aiming to understand details of the transport of matter during irreversible plastic deformation. From this understanding, the microstructure can be modified to impede the matter transport and thus to make the material even harder. See also Kizler et al. Computational Materials Science 39 (2007) 205-213.

St. Mary's Church (Marienkirche) in Reutlingen was build from 1247 to 1343 and is one of the most distinct Gothic buildings in South-West Germany. The octagonal tower roof consist of a local sandstone and was repaired several times due to lightnings, earthquakes and fires. One of the last activities was the installation of a concrete inner shell in the fifties due to static problems. In the measuring campaign the structural behaviour of the sandstone concrete compound of the roof shell was examined by non-destructive testing with impact echo and radar techniques in three fields of different exposition. The visualisation is a horizontal cut of processed impact echo results (computed frequencies, exposition east) in a certain depth.

TAT - Institute for Theoretical Astrophysik

TAT (Institute for Theoretical Astrophysik), Universität Tübingen, Germany

In the field of astrophysics simulations of accretion disks TAT produces large numbers of 3D particle data, which have to be visualized for proper analysis and interpretation. These simulations might take several days of cpu time for calculation even on a high performance supercomputer. So far, the inspection of the simulation data was only possible after the simulation has finished. For this reason a new data exchange mechanismn was implemented that supports the visualization of data from a running simulation. The advantage of this online visualization is that a better control of the running simulation is possible. A scientist can now detect a failing simulation run earlier and stop it if necessary.

The figure shows the online visualization of the particle data from an accretion disk simulation. With using the collaborative volume renderer spatial distributed scientists can now discuss the visualization results of different simulation steps.
