WoundSIM is a new software tool targeting the design, simulation and optimization of composite pressure vessels (COPV). Although primarily used in the automotive and aerospace industries, it has been used by the United States Navy, various research centers, the education industry, and for hydrogen storage as a rapid tank design process. and efficient. It is developed, supported and maintained by Dassault Systèmes (Vélizy-Villacoublay, France), the development partners of Simulia QustomApps (Ponder, Texas, US) and S Vertical (Châtenay-Malabry, France). The first beta was released in 2019, with additional features to be included in 2022.

Under WoundSIM, a graphical interface makes it possible to instantly visualize the composite layup as the table of composite layers is defined. The accumulation of layer thickness is automatically calculated, as well as the different wind angles. The properties of the spread materials are also calculated and assigned throughout the COPV, and built-in Finite Element Analysis (FEA) translation software allows users to generate a ready-to-run FEA model to assess thermal and mechanical responses. of COPV.

The main features of WoundSIM noted include:

  • Reinforcement of the layer thickness for a better correlation with the geometry of the produced reservoirs;
  • Comprehensive design parameters allowing rapid variation in layer shape;
  • A complete and autonomous user interface;
  • Fast GUI response (
  • Smart layup rendering for easy layer selection and identification;
  • Fast and fully automated generation and post-processing of the FE model of the reservoir;
  • Full compatibility with Simulia Abaqus Unified FEA from Dassault Systèmes;
  • Automated conversion of Abaqus WCM models;
  • Compatibility with Simulia Isight for advanced parametric optimization;
  • Public XML API to ensure compatibility with other winding software or customer’s internal tools and formulations;
  • Built-in parametric tank optimization capabilities to reduce tank weight;
  • And the built-in models VS test the calibration.

After defining and visualizing the layup in the WoundSIM interface, users can generate the geometry of the tank and the corresponding FEA models in order to perform all the necessary simulations. The models generated include reservoir layer geometry and improved reservoir mesh generation; properties of processed materials; automated assembly with other tank components; loads and definitions of boundary conditions; and the ability to generate 2D, 3D, shell and solid models. The Abaqus / CAE models can also be edited and enriched by the user.

All load cases required to design the tank can be performed on the generated FE models, including static / dynamic burst pressure, heat transfer analysis, coupled temperature displacement, drop tests, and dynamic impacts and cyclic and fatigue assessment. The fracture stress and fracture strain parameters can also be included in the FE analysis for realistic prediction of composite layer failure.

Additionally, the WoundSIM-to-Abaqus interface provides a number of seamless post-processing capabilities such as specialized path and contour plotting tools for rapid assessment of reservoir response. WoundSIM includes a compiled user routine library that provides access to all composite-specific output post-processing amounts, such as wrap angles, fiber matrix stresses and strains, and damage parameters .

Finally, WoundSIM offers advanced engineering capabilities and built-in algorithms that provide multiple capabilities to composite tank designers and simulation engineers. Some capabilities involve parametric design, experiment design, batch calculation, study of reservoir geometry variability, correlation with other winding software, correlation of models with produced reservoirs, and image processing of reservoirs.
