#### 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.
