Best practices for CFD haemodynamic modeling with Simcenter STAR-CCM+
Simulation is long established as a method for generating proof that a medical device meets a requirement. But simulation can be used in other ways as well. Watch the on-demand webinar to learn about best practices for computational fluid dynamics (CFD) haemodynamic modeling and how other organizations have used simulation for diagnosis and intervention planning.
Simulation is not useful unless it is credible. There must be trust in the predictive capabilities of a computational model in the specific context of where it is being used. Once that credibility is established, organizations can use simulation all throughout the design lifecycle. From early concept building where costs are relatively low, simulation can help to reduce the number of prototypes needed and therefore the ability to get a product to market sooner.
The majority of CFD haemodynamic studies use velocity inlet–pressure outlet boundary conditions. The inlets are prescribed to be the velocity or mass flow waveforms. In regard to outlets, there are a few options, including zero-pressure or “bleeding out” outlet, prescribed flow split percentages based on daughter vessel areas, or Windkessel models. Lastly, for walls, non-slip conditions versus fluid-structure interaction methods can be used.
