Facts

Purpose
FEniTop is open-source software for topology optimization based on FEniCSx.github.com · 4 Oct 2026
Dimensions and meshes
It supports 2D and 3D problems with structured or unstructured meshes and multiple element geometries and types.github.com · 4 Oct 2026
PDEs and sensitivities
It expresses PDEs in weak form and uses automatic differentiation for finite-element analysis and sensitivity analysis.github.com · 4 Oct 2026
Parallel computing
It supports scalable parallel computing on systems ranging from laptops to distributed computing clusters.github.com · 4 Oct 2026
Filtering
It includes a Helmholtz-type PDE filter designed for large-scale parallel problems, including problems with large filter radii.github.com · 4 Oct 2026
Export
Optimized designs can be exported as XDMF files for post-processing in ParaView.github.com · 4 Oct 2026
Examples
The repository includes examples for 2D and 3D beams, a 2D disk, a 3D shell, and a 2D compliant mechanism.github.com · 4 Oct 2026
Requirements
The installation instructions specify FEniCSx version 0.7.3, PyVista, and Xvfb.github.com · 4 Oct 2026
Windows setup
The documented Windows 11 setup uses WSL with Ubuntu, Docker Desktop, and a Docker image containing FEniCSx, PyVista, and Xvfb.github.com · 4 Oct 2026
License
