    • A. Münch (University of Oxford) and D. Peschka (Weierstrass Group) organised the minisymposium ”Recent advances in understanding suspensions and granular media flow” at the 9th International Congress on Industrial and Applied Mathematics (ICIAM 2019) in Valencia, Spain, 15th -- 19th July, 2019.
    • From 1st June to 31st July, 2019, Luca Heltai, (SISSA, Trieste) was a visitor of the Weierstrass Group and researched on the subject of FEM-based discretization methods.
    • On 31st January and 1st February, 2019, the kickoff meeting of the ECMI Special Interest Group ”Modelling, Simulation and Optimization in Electrical Engineering” took place at WIAS; the meeting was organised by Nella Rotundo (RG1), Patricio Farrell (RG3) and Dirk Peschka (Weierstrass Group).
    • Analysis of Evolutionary and Complex Systems (ALEX2018), 24th -- 28th September, 2018



    Research goal of the group is the development of mathematical methods for systems with bulk-interface processes for the
    • thermodynamically consistent modeling of bulk-interface interaction with dissipative, Hamiltonian, and coupled dynamics,
    • theory for the existence and qualitative properties of solutions,
    • derivation and justification of interfacial processes and coupling conditions.

    The analytical results form the basis for the development of numerical algorithms supporting simulations for applications with bulk-interface interaction.

    Currently, the following applications are treated within the group:

    Mechanical stresses and progression of damage for a tension test with a notched bar using a BV-regularized damage model Cross-section through a laser-device: The optically active germanium region displays the hole currents (colors) and the contour lines of the main mode (red lines) P1 FEM solution of free boundary problem showing thin droplets sliding down an inclined plane
