Abstract
High-Performance Computing has recently been challenged by the advent of Artificial Intelligence. Artificial Intelligence has become rather popular in the last years and has claimed some success in solving relevant scientific problems in a variety of fields. In this paper we will look at the question of whether these technologies are mutually exclusive or whether they complement each other. We will argue that High-Performance Computing and Artificial Intelligence are two technologies that work together well. We will further argue that they are complemented by the Internet of Things which helps to create a concept that we want to call Digital Convergence. We will furthermore explore, how this Digital Convergence already today shapes the future of computer simulation. We will finally point at some new types of problems that will benefit from this Digital Convergence.
Towards the simulation of bone-implant systems with a stratified material model

Abstract
BACKGROUND: The clinical performance of medical devices is becoming increasingly important for the requirements of modern development processes and the associated regulations. However, the evidence for this performance can often only be obtained very late in the development process via clinical trials or studies.OBJECTIVE: The purpose of the presented work is to show that the simulation of bone-implant systems has advanced in various aspects, including cloud-based execution, Virtual Clinical Trials, and material modeling towards a point where and widespread utilization in healthcare for procedure planning and enhancing practices seems feasible. But this will only hold true if the virtual cohort data build from clinical Computer Tomography data are collected and analysed with care.METHODS: An overview of the principal steps necessary to perform Finite Element Method based structural mechanical simulations of bone-implant systems based on clinical imaging data is presented. Since these data form the baseline for virtual cohort construction, we present an enhancement method to make them more accurate and reliable.RESULTS: The findings of our work comprise the initial step towards a virtual cohort for the evaluation of proximal femur implants. In addition, results of our proposed enhancement methodology for clinical Computer Tomography data that demonstrate the necessity for the usage of multiple image reconstructions are presented.CONCLUSION: Simulation methodologies and pipelines nowadays are mature and have turnaround times that allow for a day-to-day use. However, small changes in the imaging and the preprocessing of data can have a significant impact on the obtaind results. Consequently, first steps towards virtual clinical trials, like collecting bone samples, are done, but the reliability of the input data remains subject to further research and development.
