Z88Arion
Z88Arion is a graphical program for topology optimization based on the Z88 finite-element analysis software.
What Z88Arion is
Z88Arion is a graphical program for topology optimization based on the Z88 finite-element analysis software. It offers OC, SKO, and TOSS optimization methods and can import STEP geometry, ASCII or binary STL files, and NASTRAN, ABAQUS, COSMOS, and Z88 project files. Its preprocessing tools include tetrahedral, adaptive tetrahedral, and mapped hexahedral meshers. Users can edit a material database containing 50 predefined materials and set boundary conditions through the graphical interface. The postprocessor displays optimization 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 available in German, while an English version is under development. Private, research, educational, training, and test use do not require a separate license; commercial users can request a free individual license. The program includes examples, help documents, and videos, while workshops are offered in German. Its freeware plan is free.
