Using Multi-Physics Simulation for Accelerated Medical Device Prototyping: FEA and CFD Integration in Design and Development

Bhanu Prakash Mettu

Abstract: Medical device prototyping gets a major boost when Finite Element Analysis (FEA) is combined with Computational Fluid Dynamics (CFD) in multi-physics simulation modeling. Using FEA and CFD together helps check that implants and surgical tools are strong and can handle stress and fatigue. They also model how fluids move and how heat is transferred in devices like catheters, respiratory machines, and surgical pumps. These simulation techniques allow a full fluid-structure interaction (FSI) analysis for complex devices such as stents and heart valves. The combined method cuts down the number of physical prototypes by 40?60%, saving development time and money, and helps meet FDA and CE rules. Yet, the method has two main issues: high computer power is needed and it is hard to mesh complex anatomical models accurately. Advanced solvers and AI-driven optimization, together with cloud-based high-performance computing (HPC), help overcome these challenges. This paper looks at the technical challenges of FEA-CFD integration, compares its performance to traditional methods, and discusses new trends in medical device development.
