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

SmartDO 2025 introduces OpenXim, a platform that helps connect open-source CAD/CAE tools through data streaming and linking.

This makes it easier to create a smooth and high-performance design optimization process that works across various engineering software platforms.

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

SmartDO 2025 gives more power to the open-source engineering community through better design optimization.

It uses advanced nonlinear-programming methods and the latest computing technologies to improve efficiency.

Integrated with FreeCAD, PrePoMax, and CalculiX, it supports multiple types of analysis like linear and nonlinear static, stress analysis, assembly stress, sub-modeling, and handling nonlinear effects like buckling, contact, and rubber behavior.

It also enables modal, dynamic, harmonic, thermal, and thermo-mechanical simulations. This helps engineers get faster results, better insights, and advanced global optimization directly in their workflow.

Some Analysis Types Supported by PrePoMax/Calculix.

Platform for Synchronizing Geometry/Settings Between Open-Source and Commercial CAD and Open-Source CAE

Through OpenXim, SmartDO now makes it easy to connect commercial and open-source tools.

From FreeCAD, SOLIDWORKS, and NX to PrePoMax and CalculiX, all geometry and data move smoothly in real time. This setup, called SmartLink, lets users keep geometry and settings in sync, manage parameters easily, and use AI-driven optimization all in one simple configuration.

Figure 1 shows the architecture of the OpenXim platform.

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

Here’s a simple example of SmartDO’s syncing abilities: a six-variable shape optimization problem using FreeCAD for geometry, PrePoMax for meshing and boundary setup, and CalculiX for nonlinear FEA.

The goal is to reduce the structural volume while keeping the Von Mises stress below 150 MPa. Figure 2 shows the model geometry and the design variables.

The final optimized design by SmartDO:

Initial volume: 164,265.2 mm³

Optimized volume: 74,216.3 mm³

All design constraints were met

SmartDO used about 130 Calculix analyses to reach the best solution

Figure 3 shows the changes in shape during the design process.
