FEACFDTools

FEACFDTools is an open-source software toolkit designed to support integrated finite element analysis (FEA) and computational fluid dynamics (CFD) workflows. It provides a common data model, solver interfaces, and utility components to enable multi-physics simulations across disciplines such as structural mechanics, heat transfer, and fluid dynamics. The project emphasizes modularity, cross-language access, and interoperability with common file formats and visualization tools.

Key components include a mesh and field data manager, physics modules for various regimes, a solver abstraction layer with interchangeable backends, and pre/post-processing interfaces. It supports time-stepping, nonlinear solution strategies, and coupled simulations, allowing users to assemble complete simulations from modular parts. It provides I/O facilities for formats such as VTK, CGNS, STL, and several CAD bridges, and includes basic visualization hooks through Python or external tools.

Architecture and development: The design centers on a core kernel that defines meshes, fields, boundary conditions, and material properties. Solver backends implement linear and nonlinear solvers, with an API that allows plugging in third-party libraries. A plug-in system enables additional physics models and post-processing utilities to be added without modifying the core. Python bindings and C++ interfaces support rapid prototyping and deployment across platforms.

Development and licensing: FEACFDTools is released under an open-source license and is maintained by a volunteer community of researchers and developers. It relies on community contributions, issue trackers, and documentation to evolve. The project aims for portability across operating systems and support for parallel execution on multi-core and cluster environments.
