WoundSim
The new generation software to design and simulate composite pressure vessels (COPVs)
WoundSim offers a long-term solution with a strong commitment from S VERTICAL and QustomApps companies for support, maintenance, and future development.
WoundSim is a next-generation engineering software dedicated to the design, simulation, optimization and manufacturing of filament winding composite pressure vessels (COPVs). Built on more than ten years of expertise in composite pressure vessel engineering, WoundSim has been developed by mechanical and software engineers to address the technical challenges and complexity associated with COPV design and analysis.
The software delivers a modern and intuitive user experience focused on engineering efficiency, enabling users to perform fast, accurate, and reliable simulations while simplifying the overall design workflow. WoundSim is fully compatible with the finite element environment of SIMULIA and Dassault Systèmes Abaqus Unified FEA technology, ensuring industrial-grade simulation reliability.
Designed as a long-term engineering platform, WoundSim reflects the strong commitment of S VERTICAL to continuous innovation, technical support, maintenance, and future development, helping companies accelerate COPV product development while improving structural performance and manufacturing readiness.

From WoundSim to FEA Model
After the layup definition and visualization in WoundSim interface, users can generate the reservoir geometry and the corresponding FEA models in order to perform the needed simulations. The generated Abaqus models are ready-to-run and they include:
-
Layer geometry and partitions
-
Clean reservoir mesh generation
-
Transformed material properties
-
Assigned sections based on bins
These simulation models will allow running a series of
simulations to verify all requested reservoir requirements:
-
Static and Dynamic burst pressure
-
Thermal Expansion
-
Dynamic drop tests and impacts
-
Cyclic and fatigue assessment
