31.01.-01.02.2019, WIAS Berlin, Kick-off Meeting of the ECMI Special Interest Group "Modeling, Simulation and Optimization in Electrical Engineering (MSOEE)"
OverviewResearch 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:
- dissipative processes in elastic solids with bulk-interface interaction (M. Thomas), such as e.g. damage, fracture, plastification,
- optoelectronic processes in semiconductor devices (M. Thomas, D. Peschka),
- viscous flows with free boundaries and contact lines (D. Peschka).
