End-to-End Automated Workflow for COPV Design Optimization

Multi-Objective & Multi-Constrained Parametric Optimization Algorithm

Our advanced design optimization algorithm enables the development of robust and lightweight COPVs (Composite Overwrapped Pressure Vessels) with a 20–40% reduction in material usage, all while maintaining the strength required to withstand high internal pressures.

The optimization procedure is powered by a combination of Finite Element Analysis (FEA), using CPVAdvisor’s built-in Model Builder and FEM Solver, and a custom, multi-objective optimization algorithm. This advanced workflow enables precise evaluation and refinement of designs while considering critical engineering factors.
