PROFILE

Philipp Schäfer

Worked on the 4C-multiphysics/4C repository, focusing on enhancing multiphysics simulation reliability and accuracy. Developed a Nitsche-based time integration scheme for poroelastic contact, refactoring the contact strategy to support robust coupling of poroelasticity with contact conditions. Added validation tests to ensure correctness and regression safety, improving confidence in simulation results. Addressed a critical issue in time integration by preventing double counting of material damping and ensuring correct handling when damping is set to 'none.' Utilized C++, cmake, and the Finite Element Method, applying advanced numerical integration and software engineering practices to improve solver stability and maintainability.

November 2024 performance summary for the 4C project focusing on poroelastic contact. Delivered a robust time-integration enhancement using the Nitsche method, refactored the contact strategy to support the new integration, and added validation tests to ensure correctness and regression safety. The work improves simulation accuracy and robustness under poroelastic contact conditions, enabling more reliable physics-based predictions and broader application potential in poroelasticity modeling.

Month 2024-10: Delivered a critical damping handling fix in the 4C time integration, preventing double counting of material damping and ensuring zero damping when damping type is 'none'. The change aligns the new time integration behavior with the legacy timint, improving numerical fidelity and reliability for multiphysics simulations.
