Using SmartDO 2025 to Power the Freedom of Open Source CAD/CAE with OpenXim and Cutting-Edge Computing Efficiency

SmartDO 2025 introduces OpenXim, an platform for integrating open-source CAD/CAE tools via data streaming and linking, delivering a seamless, high-performance design optimization workflow across diverse engineering platforms.

SmartDO Smart Design Platform to Power the Freedom of Open Source CAD/CAE

SmartDO 2025 empowers the open-source engineering ecosystem with advanced design optimization, combining nonlinear-programming algorithms and cutting-edge computing efficiency.
Integrated with FreeCAD, PrePoMax, and CalculiX which supports linear/nonlinear static, assembly stress analysis, sub-modeling, and nonlinear effects like buckling, contact, and rubber. It also enables modal, dynamic, harmonic, thermal, and thermo-mechanical simulations. The result: faster iterations, deeper insights, and next-generation global optimization, right at your fingertips.

Platform for Synchronizing Geometry/Setting between Open-Source/Commercial CAD and Open-Source CAE

Through OpenXim, SmartDO now enables seamless integration between commercial and open-source tools. From FreeCAD, SOLIDWORKS and NX to PrePoMax and CalculiX, all geometry and data stream smoothly in real-time. This push-button SmartLink setup supports synchronized geometry updates, streamlined parameter management, and AI-driven optimization pipelines — all in a single-page configuration.

A Simple Example: Structural Shaping Optimization with SmartDO + FreeCAD + PrePoMax + CalculiX

Here is a simple example showing SmartDO’s synchronizing capabilities : a six-variable shape optimization problem using FreeCAD (geometry), PrePoMax (meshing and boundary setup), and CalculiX (nonlinear FEA).
The objective is to minimize structural volume, with constraint of Von Mises stress < 150 MPa. Figure 2 shows the geometry and design variables of the model.

The final optimized design by SmartDO :

• Initial volume: 164,265.2 mm³
• Optimized volume: 74,216.3 mm³
• All design constraints satisfied
• SmartDO took about 130 Calculix analysis to reach the optimum.
