In-silico Medicine – Virtual Clinical Trials


Computer Modelling and Simulation

Computer Modeling and Simulating (CM&S) has the potential to accelerate the long and challenging development process of medical devices and to move faster to the market, while reducing significantly costs associated with development and V&V activities. International regulatory agencies like EMA or FDA are recognizing the vast opportunities of making CM&S the fourth column in the medical device development process, besides bench-top testing, in-vitro, and in-vivo studies.

4RealSim Life Sciences is a leading service provider in that field and offers a large array of sophisticated multi-physics simulation processes & tools that support all phases of the medical device development process – from virtual feasibility studies via classic device verification and validation analyses to augmenting your human clinical studies with corresponding modelling and simulations – the in-silico trial. We offer in the simulation services for the following physical domains:

  • Structural Mechanical Analyses
  • Computational Fluid Dynamics
  • Fluid-Structure Interaction
  • Heat-Transfer Analyses
  • Coupled Heat-Stress Analyses
  • Electromagnetic Analyses
