In their own words
FEniTop
FEniTop is free, open-source software for topology optimization based on FEniCSx. It handles two- and three-dimensional problems on structured or unstructured meshes, with varied element geometries, types, orders, and quadrature degrees. Users express partial differential equations in weak form, while automatic differentiation supports finite-element and sensitivity analysis. PETSc through petsc4py provides linear and nonlinear solvers and preconditioners. Parallel implementations of Optimality Criteria and Method of Moving Asymptotes update design variables. A Helmholtz-type PDE filter targets large-scale parallel problems, including large filter radii. FEniTop can run from laptops to distributed computing clusters. Optimized designs export as XDMF files for ParaView post-processing. Repository examples cover beams in 2D and 3D, a 2D disk, a 3D shell, and a 2D compliant mechanism. The software is licensed under GPL-3.0. Setup instructions specify FEniCSx 0.7.3, PyVista, and Xvfb; Windows 11 instructions use Ubuntu under WSL and Docker Desktop.
Z88Arion
Z88Arion is a graphical structural optimization program for topology optimization, built on Z88 finite-element analysis software. It provides OC, SKO and TOSS algorithms; imports STEP, ASCII STL, binary STL, NASTRAN, ABAQUS, COSMOS and Z88 project files; and includes tetrahedral, adaptive tetrahedral and mapped hexahedral meshers. The editable material database contains 50 predefined materials, and boundary conditions are set through the graphical interface. Its postprocessor visualizes results, smooths geometry, exports smoothed geometry to STL and connects directly to Z88Aurora. The current release is Z88Arion V3 for 64-bit Windows, with compatibility listed from Windows 7 through Windows 11. The current version is German, while an English version is under development. The Freeware plan costs nothing. Private, research, educational, training and test use need no separate license; commercial users can request a free individual license.
