title: [Tackling hemodynamic analysis of the carotid artery using open-source software and computational fluid dynamics].
abstract: OBJECTIVE
  The aim of this study was to evaluate the impact of wall share stress (WSS) in the carotid artery using a computed fluid dynamics analysis system and adopting open-source software.
  
  
  METHODS
  The dependence of element number (computation time and analytical accuracy) were considered with simple vessel models. We evaluated WSS and flow velocity using a carotid artery model that was based on the outcome of simple vessel models.
  
  
  RESULTS
  When the number of elements was 10(5) or more, the flow velocity error of the outlet decreased to 0.5% or below when using simple vessel models. The carotid bifurcation model showed a whirlpool and a decrease in flow velocity in the carotid bulb part.
  
  
  CONCLUSIONS
  An analysis system was built using open source software. The results from the carotid bifurcation model suggested that hemodynamics contributes to the development of carotid stenosis.
