Overview

ProTOp Professional is a standalone, high-performance topology optimization solution built for engineers who need powerful, production-ready results. It supports FNF, INP, GEO, and DAT files generated by leading platforms such as PTC® Creo®, Simulia® Abaqus, SolidWorks® Simulation, and Siemens NX™, making it easy to integrate into existing simulation and design workflows. With fast solvers and robust optimization engines, ProTOp streamlines the creation of lightweight, efficient, and manufacturable designs.

The software offers advanced design capabilities through efficient shell and lattice configurators, delivering full 3D solid models that are ready for downstream engineering or additive manufacturing. Its fully interactive environment includes high-quality visualization, smoothing, and post-processing tools, enabling users to refine geometry and prepare optimized models directly for 3D printing. For teams seeking cutting-edge topology optimization with practical, real-world output, ProTOp is a powerful and flexible choice.

What's New

Reference node targeting in stress topology optimization; various reference node response values of individual load cases can now be used for targeting in topology optimization.
Improved response fields display; only selected volume regions and individual displacement components can be displayed now.
