FEniCS26 in Paris
Mid-June, members of the Computational Applied Mechanics group attended the FEniCS2026 Conference in Paris.
During the event, Johannes Neumann and Lavakumar Veludandi shared our latest research utilizing FEniCSx with an amazing community of mathematicians, computer scientists, and domain experts.
They delivered two talks covering different facets of computational mechanics:
Johannes Neumann presented in the Engineering Applications session on: “Finite-Element Modeling of Complex Inelasticity Using FEniCSx: Paper and Thermoplastics”. This work presented constitutive models for simulating the inelastic and coupled thermomechanical responses of paper and thermoplastics, relying on FEMExternal Operators and JAX for local solution schemes and the automatic differentiation of consistent tangents.
Lavakumar Veludandi presented in the Solid Mechanics session on: “Computational Shakedown Analysis with FEniCSx: Conic Optimization for Large-Scale FEM”. This presentation introduced a modular framework for lower-bound shakedown analysis natively integrated within the FEniCSx ecosystem, coupling finite element formulations with large-scale conic optimization backends (such as MOSEK or Gurobi) while maintaining explicit control over constraint sparsity.
Beyond the presentations, the true highlight of FEniCS2026 was the vibrant networking and community spirit. Having dedicated time to discuss ideas, troubleshoot codes, and exchange perspectives directly with core FEniCS Project developers and fellow users was an invaluable experience. It truly showcased the power of open-source ecosystems in driving modern scientific research forward.
Many thanks to the FEniCS Conference 2026 Organizing Committee for hosting an excellent and well-organized event. We returned to Wuppertal with great feedback and look forward to continuing our work with the FEniCS community.
