CAESES vs SmartDO

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.

SmartDO is a multidisciplinary, multiphysics platform for automatic engineering design optimization. Its Direct Global Search can begin an optimization after setup with one button, without a design of experiments or manual sensitivity study. The maker describes S.A.F.E.D. and SmartLearning as features that can bypass failed CAD or CAE runs and use earlier calculations to reduce computational cost. APO supports synchronous multi-objective optimization without user weighting. SmartDO uses Tcl/Tk and Python, allowing add-ons, GUIs, graphics, and plotting tools. SmartLink connects the platform with CAE packages, while OpenXim links commercial or open-source CAD with simulation software. Named examples include ANSYS Workbench, FreeCAD, SOLIDWORKS, NX, PrePoMax, and CalculiX. The software page reports successful use with more than 240 design variables and 132 constraints. FEA-Opt Technology develops SmartDO and offers consulting and integration services. Pricing is available on request.
