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, the new generation software for designing, simulating and optimizing filament winding pressure vessels (COPVs). Strong with more than 10 years' experience on composite pressure vessels, WoundSim developers and mechanical engineers have addressed the many challenges and complexities which arise during the design and simulation of COPVs. The result is a tool providing a new user experience which is simple, fast and greatly simplifies the design process for COPVs. Fully compatible with Dassault Systèmes SIMULIA Abaqus Unified FEA, WoundSim offers a long-term solution with a strong commitment from S VERTICAL and QustomApps for support, maintenance, and future development.

Mike SHUBERT the ex-developer of WCM plugin is now one of the developers of WoundSim, for this reason WoundSim can be considered as the replacement solution for WCM plugin developed by SIMULIA brand.


Example tank model



WoundSim is a set comprehensive features that ensure a rapid design and simulation of the pressure vessels.
Principal features are listed below:

  • Democratized tool with a comprehensive and standalone user interface.

  • User interface short time response, accelerating design duration.

  • Comprehensive and well-chosen design parameters allowing a quick variation of the layers shape.

  • Fully automated FEA models generation, allowing performing simulations with minimum FE knowledge.

  • Winding problems anticipation.

  • Smart layup rendering allowing layers selection and intersections detection.

  • Design of experiment capabilities for parametric design optimization.

  • Full compatibility with Abaqus software and no need for Fortran compiler to post-process specific material outputs.

  • Compatibility with filament winding software.

  • Models calibration and correlation with produced reservoir measurements.

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. Just like WCM plugin, 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



WoundSIM includes advanced material properties allowing advanced post processing and composites layers failure prediction.

The pre-compiled user subroutine gives access to advanced outputs such us
winding angles, fiber & matrix stresses and strains, damage parameters and composite-liner interface damage.


The WoundSIM-to-Abaqus interface provides a number of seamless post processing capabilities such as specialized path plotting and contour plotting tools, just like the ones included in the WCM plugin.



WoundSIM offers advanced engineering capabilities and integrated algorithms that allow several capabilities for composite reservoir designers and simulation engineers.

  • Some of these capabilities are listed below:

  • Parametric design capabilities

  • Design of Experiment

  • Batch computing

  • Reservoir geometry variability study

  • Correlation to other winding software

  • Models correlation with produced reservoirs

  • Reservoirs images processing
