CAESES vs Z88Arion

CAESES is a parametric engineering platform for simulation-driven design, geometry variation, and shape optimization. Its NURBS modeling tools support geometry creation and variation, while morphing tools can alter imported geometries. Software connectors can automate workflows spanning geometry generation, meshing, simulation, post-processing, and evaluation. Available methods include parameter studies, sensitivity analysis, single- and multi-objective optimization, and surrogate modeling. Listed integrations include ANSYS Workbench and optimization tools such as HEEDS, Dakota, optiSLang, Optimus, and modeFRONTIER. CAESES does not include simulation solvers, so users connect external CFD or other simulation software. The Standard Edition includes geometry modeling, software connections, design studies, variation and optimization strategies, morphing, design variants, and batch mode. The Batch Mode License adds non-GUI operation and HPC cluster optimization; the Power Edition includes advanced optimization and a maritime, turbo, or propeller add-on. Pricing is available on request, with no free plan. Windows and Linux downloads include a free two-week trial; listed systems include Windows 11 and Linux tested on Debian 12 and Ubuntu 24.04.

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.
