SNAP® is designed to simplify the process of engineering analysis. SNAP® features a flexible framework for interacting with a variety of engineering and analytical applications.
Created to Simplify Your Work
SNAP® is a robust desktop application suite that provides users with an expansive toolset and visual interface to handle large input models for some of the most powerful applications and software packages in the engineering industry.
The SNAP® Core and RELAP5 Plug-In are NQA-1 (Nuclear Quality Assurance) compliant, ensuring the highest level of control, traceability, and regulatory readiness. Trusted by organizations in safety-critical industries, it supports rigorous documentation, auditability, and process integrity — giving you confidence in every step.
Plug-In Architecture
SNAP® software is built on a powerful plug-in architecture that lets users easily extend functionality and integrate with third-party applications to fit your exact needs. Whether adding new features or tailoring the experience, SNAP’s® modular design keeps you agile without changing the core system.
Customize to Your Needs
We don’t believe in one-size-fits-all. Our development team works directly with customers to tailor the software to your specific requirements — from custom features to workflow adjustments — ensuring it aligns perfectly with your processes and goals.
