Verification, Validation, and Qualification

Verification, Validation, and Qualification

Venue:      Aerotak, Transformervej 14, 2860 Søborg

Date:         8 April 2026

Digital verification is transforming how we design, validate, and certify industrial processes and equipment. Traditionally, verification has relied on physical testing, documentation, and manual procedures, but digital tools now make it possible to demonstrate compliance virtually faster, safer, and more transparently.

This seminar focuses on digital verification of processes and equipment with emphasis on Good Manufacturing Practice (GMP) requirements, certification procedures, and ATmosphères EXplosives (ATEX) compliance. A key theme is the credibility and reliability of using Computational Fluid Dynamics (CFD) and other numerical methods in verification and approval processes.

Digital twins and advanced simulations offer great potential to improve understanding of process behavior and support documentation for regulatory approval. However, they also raise new questions: How do we ensure that a simulation is trustworthy? What are the best practices for model validation and uncertainty assessment? And how can digital verification be integrated into established quality systems and certification frameworks?

In this seminar, experts from industry and academia will present experiences, methods, and case studies on digital verification, validation of models, and the use of CFD for compliance documentation. Presentations will highlight how digital verification can reduce time-to-certification, enhance process safety, and improve decision-making.

Programme

Time Activity / Title Description
09:00 Registration and Coffee  
09:30 Introduction and motivation
Thomas Filholm, Aerotak
 
09:45 Pharmaceutical Qualification and Validation – Past, present and future
Victor Bechmann, Pharmakon / Kuatro-group
The talk starts with the Devonport accident and what it teaches about engineering responsibility. It then explains why qualification and validation are necessary, and outlines the structure and logic of the V-model. Next, it clarifies the stakeholder landscape — manufacturer, supplier, and authority — and their respective roles. The talk concludes with a forward-looking perspective on how CFD, design leveraging, and AI are changing qualification and validation practices.
10:30 Coffee break  
11:00 Validation of Cleanrooms
Ulla Thomsen og Anne Rasmussen, Novo Nordisk
A historical perspective of validation of cleanrooms
11:30 Virtual Temperature Mapping
Joachim Toftegaard Hansen, Aerotak
Temperature mapping is a critical part of qualifying temperature-sensitive spaces. In recent years, CFD has emerged as a powerful supplement to physical testing. This talk explores how virtual temperature mapping is used for qualification, highlighting the challenges, benefits, and potential pitfalls when simulations replace or reduce traditional test protocols.
12:00 Lunch and networking  
13:00 Efficient simulation of safety-critical ship maneuvers: A numerical and experimental study
Rasul Niazmand Bilandi, Force Technology
This presentation focuses on CFD simulations of a fixed-pitch propeller under crash-stop conditions. During a crash stop, the vessel continues moving forward while the propeller reverses rotation, producing negative thrust and highly transient loads. The resulting flow is strongly unsteady, with pronounced separation, recirculation, and large vortical structures that influence stopping distance and blade loading. Different simulation approaches for this safety-critical maneuver are compared and validated against experimental data. Despite the complex flow, the RANS/MRF approach shows good agreement with experiments while requiring significantly less computational effort than scale-resolving methods.
