MIS CPER program (Modeling, Interaction and Simulation, “Contrat de Plan État-Région Lorraine”)
In the frame of the MIS program (Modeling, Interaction and Simulation) of the CPER (“Contrat de Plan État-Région Lorraine”), we coordinate the MOVIS action, with participants from ALICE, ScalableGraphics , ORPAILLEUR, and Gocad . The goal of this action is to design new algorithms for modeling and visualizing both industrial and manufactured objects. In 2008, about visualization aspects, we continued to develop algorithms for visualizing molecular surfaces, industrial structures, detailed objects. We also made our linear solver on the GPU more efficient and more general.
AOC CPER program (“Contrat de Plan État-Région Lorraine”)
In the frame of the AOC program (Analysis, Optimization and Control) of the CPER (“Contrat de Plan État-Région Lorraine”), we participate to the “swimmer” action, coordinated by Marius Tucsnak (CORIDA project-team). The goal of this action is to simulate and visualize the complex fluid-solid interactions caused by a swimming fish. Last year (2007), we designed a new software library for extending MATLAB, as a module of our OpenNL library. This software library, currently under development, will allow the user to easily implement finite element solvers for coupled fluid-solid dynamics. This year, we enhanced this software library, by improving the management of sparse matrices (x2 acceleration factor as compared to our previous implementation). We also interfaced GINAC, a formal computation library. This allows computing the stiffness and mass matrices directly from the equation of the function basis and the operator. Our final goal is to test the validity of our approach by implementing a 3D Navier-Stokes solver with solid-fluid interactions.
