作者：

Highlights：

• A novel extension of smoothed Finite Element Method (S-FEM) to solve three-dimensional non-Newtonian blood flow.

• The semi-SUPG/SPGP stabilization method based on S-FEM for non-Newtonian flows is developed.

• S-FEM shows remarkable robustness for the distorted mesh.

• Analysis of the performance of S-FEM on non-Newtonian blood flows.
