Hexagon updates NCSIMUL with selective simulation

Key Takeaways

• Hexagon's NCSIMUL software now features Selective Simulation for faster NC program verification and simulation
• The new capability uses GPU-accelerated Rest Stock Previews to create intermediate stock models during the NC decoding phase
• Selective Simulation reduces simulation time, allowing programmers to inspect part progression and identify issues earlier
• The feature is particularly useful in high-value machining environments with complex programs and critical stages
• NCSIMUL's latest release is available starting May 19, 2026, with full system requirements available from Hexagon

Introduction to NCSIMUL and Selective Simulation

Hexagon's Production Software division has released an updated version of NCSIMUL, a software that combines G-code verification, CNC simulation, and optimization in a digital twin environment. The latest release introduces a new feature called Selective Simulation, designed to help programmers move through long and complex programs more efficiently.

How Selective Simulation Works

Selective Simulation uses patent-pending GPU-accelerated Rest Stock Previews to create intermediate stock models during the NC decoding phase. This allows users to view part progression within the program earlier, reducing the time it takes to inspect the target operation. In a customer trial, a program with a 47-hour machine cycle required 48 minutes of sequential simulation, but with Selective Simulation, Rest Stock Previews were generated in less than two minutes.

Comparison of Simulation Methods

Benefits of Selective Simulation

The new capability expands NCSIMUL's role in preproduction workflow review, supporting NC program review and machining workflow efficiency. By combining simulation and optimization in one environment, NCSIMUL enables manufacturers to increase speed while limiting production risk. Programmers can use the previews to inspect the part state at different stages, identify visible issues earlier, and move more directly to operations that require closer review.

Conclusion and Availability

The latest release of NCSIMUL is available starting May 19, 2026, with full system requirements available from Hexagon. For more information, visit hexagon.com.

Bottom Line

Hexagon's updated NCSIMUL software with Selective Simulation is a significant improvement for manufacturers, particularly those in high-value machining environments. By reducing simulation time and allowing for faster inspection of part progression, Selective Simulation enables programmers to identify issues earlier and increase overall efficiency. With its latest release, NCSIMUL solidifies its position as a leading software for NC program verification, simulation, and optimization.
