Jul 1, 2025Month 2025-07: Delivered the Unified Entity Mapping for Mixed-Domain Interfaces (EntityMap) in FEniCS/dolfinx. This feature introduces an EntityMap class to map entities across multiple meshes, simplifying assembly of forms involving submeshes and interfaces and improving cross-domain interactions. No major bugs fixed this month. Overall impact: enables scalable multi-physics workflows, reduces cross-mesh coordination, and improves correctness for cross-domain simulations. Technologies demonstrated: multi-mesh data structures, cross-domain interface handling, and traceability to a key commit (8b2c4beb771b86d3775e8b2cd4271e541300469d).

Feb 1, 2025February 2025 monthly summary for FEniCS/dolfinx. Delivered a feature that enhances mesh entity localization across mixed topologies, enabling more flexible and robust simulations for complex geometries. The work improves the reliability of locate_entities by extending support for different entity types and updating the Topology class connectivity. This contributes directly to broader applicability of dolfinx in multi-topology scenarios and reduces manual work required from users handling mixed meshes. The change aligns with issue #3637 and is backed by a focused commit to extend locate_entities.
