Bruno Levy, researcher and director of INRIA Nancy Grand-Est is invited for a LIRIS seminar around fluid simulation and optimal transport, on Monday, February 24th, in Nautibus, room C5. Abstract: I will talk about some numerical methods to simulate incompressible fluids with free boundaries. The methods I'm interested in [Gallouet & Merigot, DeGoes et. al] decompose the fluid into a set of cells (power diagram) in such a way that the volume of each cell remains constant, hence enforcing incompressibility. The volume constraints uniquely determines the parameters of the power diagram, that can be found by maximizing a concave objective function (semi-discrete optimal transport). I will show some examples of 3D fluid simulations with free boundaries, viscosity and surface tension, as well as applications in astrophysics.

22nd MDPS/IRIXYS Workshop The 22nd edition of the IRIXYS workshop will take place from June 17th to 21th 2019 at INSA Lyon. The workshop which will gather academic and industrial representatives will be co-chaired by Ernesto Damiani, Lionel Brunie and Harald Kosch. The PhDs students from the INSA Lyon, the Università degli Studi di Milano and the University of Passau will do presentations reporting about their research works.

Justin Solomon, associate professor at the Massachusetts Institute of Technology ( http://people.csail.mit.edu/jsolomon/ ) will give a LIRIS seminar titled Correspondence and Optimal Transport for Geometric Data Processing.
