Aims
Investigating the parameterized uncertainties of the blood flow in a centrifugal blood pump instrument. By quantifying the uncertainties in the numerical model in order to further improve the engineering design of the machine and guarantee the surgical process.
Why using HiFlow³?
HiFlow³ provides the viability of employing the Stochastic Finite Element Method (SFEM) based on the generalized Polynomial Chaos (gPC) method with advanced solver/preconditioner techniques to accelerate the computation. The flexible grid implementation enables also the moving mesh technique to achieve the rotating machinery modeling.
